How to determine cubic volume. How to calculate the volume of a container of various shapes

Quite often in life there are situations when it is necessary for some material to calculate the volume in cubic meters. It can be done different ways, and in this article we will look at a few of them.

Calculation of volume by linear dimensions

If the material is stacked and it is possible to measure its linear dimensions, consider yourself very lucky. To calculate the volume, it will simply be enough to multiply the length, width and height. Let me remind you that a cubic meter is the volume of a cube with sides of 1m. If measurements are made in centimeters, then 1m 3 \u003d 1,000,000 cm ?. It is possible that you need to calculate the volume of boards or bricks, knowing their number. In this case, the calculation is also not difficult: we measure the length, width and thickness of the board and multiply by the number of pieces.

You can at least approximately calculate the volume of material poured into a pile. The pile is close to a cone in shape, and the volume of the cone is calculated by the formula V=πR 2 h/3, where h is the height and R is the radius of the base. The volume of material in a cylindrical container (barrel) can be calculated using the formula: V=πR 2 h, where h is the height and R is the radius.

Calculating volume by weight

It happens that there is no way to measure the linear dimensions. This situation arises, for example, when working with bulk goods, liquids and gases. Or, let's say, you need to understand how to calculate the cubic meter of concrete fragments, where each piece has its own shape and size. There is a good way for such a case. If we know the density of a substance, then we can determine the volume based on the weight. I think everyone remembers from school days that a liter of water weighs 1 kg. 1l \u003d 1dm 3 \u003d 0.001m 3, therefore, 1 cubic meter of water weighs 1 ton.

It is useful to remember the specific gravity for at least the most common materials:

  • Asphalt - 1.1-1.5 t / m 3
  • Concrete - 1.8-2.5 t / m 3
  • Clay dry - 1.8 t / m 3
  • Granite - 2.5-3 t / m 3
  • Fresh pine - 0.4-1.1 t / m 3
  • Oak fresh - 0.93-1.3 t / m 3
  • Brick - 1.4-2.0 t / m 3
  • Ice (at t=0C) - 0.9167 t/m 3
  • Chalk - 1.8-2.6 t / m 3
  • Dry sand - 1.4-1.6t / m 3
  • Hard coal - 1.2-1.5 t / m 3
  • Cement - 0.8-2.0 t / m 3
  • Blast furnace slag - 2.5-3.0 t / m 3

Law of Archimedes

If you want to calculate the volume of a certain body irregular shape, whose material density is unknown, you can use the famous law of Archimedes. Having immersed the body in water, measure how much the water level has risen. The volume of water displaced is the volume of the body.

How to measure a cubic meter

This method is, of course, quite laborious. But in some situations, it may be the only possible answer to the question regarding how to calculate a cubic meter. You can measure a cubic meter of material, for example, using a bucket. A standard bucket has a capacity of 10 liters, or 0.01 m3. Thus, 100 buckets of material - this will be our desired cubic meter.

You should start with the fact that all used in modern physical science and in everyday life the units of measurement are nothing but the result of painstaking work scientists for hundreds of years. In order to bring all inches, miles and pounds to a common denominator, we decided to switch to a common unit of measurement. The modern metric system was based on kilograms and meters. All other units of measurement are derivatives, including the cubic meter. This article will tell you how to calculate the cubic capacity of various building materials.

A cubic meter is a measure of the volume of a body or substance. A cubic meter is the volume of a cuboid figure with edges exactly one meter long. The formula for calculating a cubic meter is very simple and looks like this: 1m3 = 1mx1mx1m.

measurement in cubic meters are subject to both solid substances (for example, lumber, reinforced concrete blocks) and liquid(dwelling water consumption, concrete consumption), and gaseous(measurement domestic gas for utility bills).

Obviously, if the source information is presented in related units of measurement (for example, in liters or cubic centimeters), then their conversion to volume units will not take much time. However, if mass or area is to be converted, some additional information will be required and the calculation is more complicated.

Calculation of the cubic capacity of edged lumber:

When calculating cubature edged board you will need to apply the knowledge acquired in geometry lessons. In case of edged lumber you just need to multiply the three standard values. However, an incomplete pack of boards (beams) is taken into account. It is necessary to calculate the cubic capacity of one element first, then, having counted the total number of boards (bars) in a pack, multiply this number by the resulting volume value.

When calculating the cubature in this case need to work with the same units of measurement, i.e. convert all board sizes to meters (centimeters). Measurements should be carried out according to the parameters: length, width, thickness.

Calculation of cubature unedged board:

The calculation of cubature in this case also requires the measurement of length, width and height. The difference is that the calculation of the cubic capacity of one board becomes impossible, so we put the boards in a pack and measure it using various coefficients.

To make the calculations more reliable, it is recommended to stack the boards, then take the average of the thinnest and widest boards, add the two resulting indicators and divide in half. Thus, the average width is recognized, the width and length are measured traditional method.

In the next step, we multiply the stack width, length and width together and apply reduction factor. In accordance with GOST, this coefficient for a half-beam and for an unedged board is 0.5 and 0.63, respectively. Often, in order to simplify calculations, lumber manufacturers ship material with a coefficient of 0.7.

After one stack of lumber has been counted, you can move on to the second, third, etc.

  • columnar;
  • tape;
  • slab.

Obviously, the calculation of the cubature in each separate case individual. Let's start with the columnar foundation:

When calculating cubature strip foundation to begin with, we determine its cross section. If it is even, there should be no difficulty in calculating the cubature. In this case, we multiply the perimeter of the structure by its thickness and width. Next, follow the calculation instructions:

cubature slab foundation is calculated most easily. To determine the cubature of the slab base, you only need to multiply the length, width and thickness of the slab.

For example, it has the following data: 10, 0.4 and 10 meters. We calculate the volume by multiplying the indicators, and we get 40 m3 - the volume of concrete required.

However, it should be noted that in order to increase the strength of the slab foundation, they often resort to equipping the plates with stiffeners. If you are dealing with just such a project, in order to calculate required amount material, you need calculate separately the volume of the slab and ribs and add the resulting values.

So, we already know the indicator associated with the stove. It remains to calculate the cubic capacity of the stiffeners.

Suppose, in our case, the base has four reinforced elements with indicators of 10, 0.25 and 0.3 meters. Obviously, the volume of one stiffener is 0.75 meters. The total indicator for all ribs is 3 cubic meters (0.75 * 4). Then, to calculate the total amount of mortar required for the slab foundation, you need add the received values(40+3) and get 43 m³.

Calculation of the cubic capacity of the room

If the room you are interested in has a simple shape, then it is not difficult to calculate its cubic capacity: just multiply the exponents width, length and height of the room.

If you do not have one or more characteristics of the room, measure them using tape measure or rangefinder. In order to increase the accuracy of the measurements taken, you can measure the height and width of opposite walls twice, then add and divide the resulting value in half (find the arithmetic mean).

Let's say you know the area of ​​the room. To find the cubic capacity, you need to multiply this indicator by the height.

If the room has complicated form, to begin with, conditionally divide the room into simple figures and using geometric formulas, calculate the volume of each, then add the values.

Calculation of cubature from mass

If the mass of a substance is known for which it is necessary to calculate the volume (cubic capacity), one should first clarify the density this substance. This indicator can be measured independently or found in the density table of substances.

In order to find out the number of cubic meters, we should divide the known indicator of the mass of a substance by its density. In this case, the mass is measured in kilograms, and the density in kg / m3.

Non-standard methods for calculating cubature

If you are dealing with some kind of irregularly shaped body and at the same time you know the density of the material from which the body is made, you can use all known Archimedes' law. To do this, you just need to lower the body into water and measure the volume of water displaced from the vessel - this will be an indicator of the volume of the body immersed in water.

There is another way to calculate the cubature of a body. He quite laborious, however, in some cases is the only way out of the situation. So, you need to measure a cubic meter of material. This can be done with a bucket. If we are talking about a standard bucket, its capacity is 10 liters or 0.01 m3. Consequently, one hundred such buckets of the material of interest to us will be one cubic meter.

As you can see, the cubature calculation scheme in each individual case is very individual. Much depends on what indicators are already known and the volume of what exactly needs to be calculated. In any case, the calculation of the cubic capacity of a particular substance (concrete, water, sand, etc.) or premises very important not only in professional field, but also in Everyday life. However, to produce necessary calculations It will not be difficult for a person who is absolutely not connected with the mathematical sciences.

How to calculate the volume of a room in m3

  • If the room is rectangular, without niches and ledges, then everything is simple: we measure the length, width and height of the room and multiply all three numbers. To get the volume in cubic meters, you need to measure in meters.
  • For standard household tasks, accuracy up to a centimeter is sufficient. The result can be rounded up to two decimal places. For example: a room has a length of 5.20 m, a width of 3.43 m and a height of 2.40. Multiply 5.2 x 3.43 x 2.4 = 42.8064. The number can be safely rounded to two decimal places. We get the volume of the room 42.81 cubic meters.
  • Even easier if you already know the area of ​​the room. Then it is enough to measure only its height and multiply it by the number you know. In a similar way, one can calculate the volume of any cuboid, though matchbox, even a refrigerator.

How to calculate the volume in m3 if it is not a parallelepiped?

  • If the room has niches, ledges, or she herself complex shape, the task becomes more difficult. It is necessary to divide the space into several parallelepipeds, calculate the volume of each, and then add them up.

By the way: if you know the area of ​​​​the room, then there will be no complication. Because when calculating the area, everything is already taken into account. So just multiply it by the height of the ceiling.

  • In general, you can measure the approximate volume of any object, even the most non-trivial form, by dividing it into simple rectangular shapes. We measure each separately, calculate the volume for the parts and add up the results. It is clear that such a result will not be very accurate. And the more complex the subject, the greater the error.


What if I want to know the exact volume in m3?

There is a way to find out the volume of any object with high accuracy. But it will suit you only if this thing is not afraid of water and you have a bath right size. The fact is that according to the law of Archimedes, a body completely immersed in water will displace an amount of water equal to its volume. That is, it is enough to type full bath water, immerse an object in it, collect all the water that spills over the edges and measure its volume with any accessible way. For example, using a measuring cup.


Measuring volume with high accuracy is rather non-trivial engineering task. But high accuracy in ordinary life rarely needed. And to get an approximate result, you only need a ruler and a calculator.

One of the most interesting problems of geometry, the result of which is important in physics, chemistry, and other areas, is the determination of volumes. Doing math at school, children often ask themselves the thought: “Why do we need this?” The world around seems so simple and clear that certain school knowledge is classified as "unnecessary". But it is necessary to face, for example, transportation and the question arises of how to calculate the volume of cargo. You say that there is nothing easier? You are wrong. Knowledge of calculation formulas, the concepts of "substance density", "bulk density of bodies" become necessary.

School knowledge - practical basis

School teachers, teaching the basics of geometry, offer us the following definition of volume: the part of the space occupied by the body. At the same time, the formulas for determining volumes have long been written down, and you can find them in reference books. Mankind learned to determine the volume of a body of the correct form long before the appearance of the treatises of Archimedes. But only this great Greek thinker introduced a technique that makes it possible to determine the volume of any figure. His conclusions became the basis of integral calculus. Volumetric figures are considered to be obtained in the process of rotating flat

Euclidean geometry with a certain accuracy allows you to determine the volume:

The difference between flat and volumetric figures does not allow answering the question of some sufferers about how to calculate the volume of a rectangle. It's about the same as finding something, I don't know what. Confusion in the geometric material is possible, while a rectangle is sometimes called a cuboid.

What to do if the shape of the body is not so well defined?

Scope of complex geometric designs- It's not an easy job. It is necessary to be guided by several unshakable principles.

  • Any body can be broken down into simpler parts. The volume is equal to the sum of the volumes of its individual parts.
  • Equal-sized bodies have equal volumes, the parallel transfer of bodies does not change its volume.
  • The unit of volume is the volume of a cube with an edge of unit length.

The presence of irregularly shaped bodies (remember the notorious crown of King Heron) does not become a problem. Determining the volumes of bodies is quite possible. This is the process of directly measuring the volumes of a liquid with a body immersed in it, which will be discussed below.

Various applications for volume determination

Let's return to the problem: how to calculate the volume of transported goods. What is the cargo: packaged or bulk? What are the container parameters? There are more questions than answers. The issue of the mass of cargo will become important, since transport differs in carrying capacity, and routes - in the maximum weight of the vehicle. Violation of the rules of transportation threatens with penalties.

Task 1. Let the cargo be rectangular containers filled with goods. Knowing the weight of the goods and the container, you can easily determine the total weight. The volume of the container is defined as the volume of a rectangular parallelepiped.

Knowing the carrying capacity of the transport, its dimensions, it is possible to calculate the possible volume of the transported cargo. The correct ratio of these parameters allows you to avoid a catastrophe, premature failure of transport.

Task 2. Cargo - bulk material: sand, gravel and the like. At this stage, only a great specialist can do without knowledge of physics, whose experience in cargo transportation allows you to intuitively determine the maximum volume allowed for transportation.

The scientific method involves knowledge of such a parameter as the load.

The formula V=m/ρ is used, where m is the mass of the load, ρ is the density of the material. Before calculating the volume, it is worth knowing the density of the load, which is also not at all difficult (tables, laboratory definition).

This technique also works remarkably well in determining volumes of liquid cargoes. The liter is used as the unit of measure.

Determining the volume of building forms

The issue of determining volumes plays an important role in construction. The construction of houses and other structures is a costly business, building materials require careful attention and extremely accurate calculation.

The basis of the building - the foundation - is usually a cast structure filled with concrete. Before that, you need to determine the type of foundation.

The slab foundation is a slab in the form of a rectangular parallelepiped. columnar base- rectangular or cylindrical columns of a certain section. By determining the volume of one column and multiplying it by the quantity, it is possible to calculate the cubic capacity of concrete for the entire foundation.

When calculating the volume of concrete for walls or floors, they do it quite simply: they determine the volume of the entire wall, multiplying the length by the width and height, then separately determine the volumes of window and doorways. The difference between the volume of the wall and the total volume of openings is the volume of concrete.

How to determine the volume of a building?

Some applied tasks require knowledge about the volume of buildings and structures. These include problems of repair, reconstruction, determination of air humidity, issues related to heat supply and ventilation.

Before answering the question of how to calculate the volume of a building, measurements are taken on its outer side: the cross-sectional area (length multiplied by the width), the height of the building from the bottom of the first floor to the attic.

The determination of the internal volumes of heated premises is carried out by internal strokes.

The device of heating systems

Modern apartments and offices cannot be imagined without a heating system. The main part of the systems are batteries and connecting pipes. How to calculate the volume of the heating system? The total volume of all heating sections, which is indicated on the radiator itself, must be added to the volume of pipes.

And at this stage the problem arises: how to calculate the volume of the pipe. Imagine that the pipe is a cylinder, the solution comes by itself: we use the cylinder formula. AT heating systems pipes are filled with water, so you need to know the area of ​​​​the internal section of the pipe. To do this, we determine its inner radius (R). The formula for determining the area of ​​a circle: S=πR 2 . The total length of the pipes is determined by their length in the room.

Sewerage in the house - pipe system

When laying pipes for drainage, it is also worth knowing the volume of the pipe. At this stage, an outer diameter is needed, the steps are similar to the previous ones.

Determining the volume of metal that goes into the manufacture of the pipe is also an interesting task. Geometrically, a pipe is a cylinder with voids. Determining the area of ​​a ring lying in its cross section is a rather complicated task, but it can be solved. A simpler way out is to determine the external and internal volumes of the pipe, the difference between these values ​​\u200b\u200band will be the volume of the metal.

Determination of volumes in problems of physics

The famous legend about the crown of King Heron became known not only as a result of solving the problem of bringing “to clean water» thieving jewelers. The result of the complex mental activity of Archimedes is the determination of the volumes of bodies of an incorrect geometric shape. The main idea extracted by the philosopher is that the volume of liquid displaced by the body is equal to the volume of the body.

In laboratory studies, a measuring cylinder (beaker) is used. The volume of liquid is determined (V 1), the body is immersed in it, secondary measurements are performed (V 2). The volume is equal to the difference between the secondary and primary measurements: V t \u003d V 2 - V 1.

This method of determining the volumes of bodies is used in calculating the bulk density of bulk insoluble materials. It is extremely convenient in determining the density of alloys.

You can calculate the volume of a pin using this method. It seems difficult enough to determine the volume of such a small body as a pin or a pellet. It cannot be measured with a ruler, the measuring cylinder is also large enough.

But if you use several completely identical pins (n), then you can use a graduated cylinder to determine their total volume (V t \u003d V 2 - V 1). Then divide the resulting value by the number of pins. V= V t \n.

This task becomes clear if it is necessary to cast many pellets from one large piece of lead.

Liquid volume units

The international system of units assumes the measurement of volumes in m 3. In everyday life, off-system units are more often used: liter, milliliter. When it is determined how to calculate the volume in liters, the conversion system is used: 1 m 3 \u003d 1000 liters.

The use of other non-systemic measures in everyday life can cause difficulties. The British use barrels, gallons, bushels, which are more familiar to them.

Tasks with non-standard data

Task 1. How to calculate the volume, knowing the height and area? Typically, this problem is solved by determining the amount of coating of various parts by galvanization. The surface area of ​​the part (S) is known. Layer thickness (h) - height. Volume is determined by the product of area and height: V=Sh.

Problem 2. For cubes, the problem of determining the volume may look interesting, from a mathematical point of view, if the area of ​​\u200b\u200bone face is known. It is known that the volume of a cube is: V=a 3 , where a is the length of its face. The area of ​​the side surface of the cube S=a 2 . Extracting from the area, we get the length of the face of the cube. We use the volume formula, calculate its value.

Task 3. Calculate the volume of a figure if the area is known and some parameters are given. To additional options include the conditions for the ratio of sides, heights, diameters of the base, and much more.

To solve specific problems, you will need not only knowledge of the formulas for calculating volumes, but also other geometry formulas.

Determining the amount of memory

A problem completely unrelated to geometry: determine the amount of memory electronic devices. In the modern, fairly computerized world, this problem is not superfluous. The exact devices that are personal computers, do not tolerate approximation.

Knowing the amount of memory on a flash drive or other storage device is useful when copying or moving information.

It is important to know the amount of RAM and permanent memory of the computer. Often the user is faced with a situation where "not game in progress"," the program hangs. The problem is quite possible with a low amount of memory.

A byte and its derivatives (kilobyte, megabyte, terabyte) are considered.

1 kB = 1024 B

1 MB = 1024 kB

1 GB = 1024 MB

The strangeness in this system of recalculation follows from binary system information encoding.

The memory size of a storage device is its main characteristic. Comparing the amount of information transferred and the amount of memory of the drive, you can determine the possibility of its further operation.

The concept of "volume" is so broad that it is possible to fully understand its versatility only by solving applied problems, interesting and exciting.

And now let's move on to the main, let's talk about how to make calculations and why they are needed.

To begin with, let's take a look…

Calculating the volume of cargo is not always easy, as it seems, all this is due to the fact that boxes can be of various shapes. Calculating the volume of cargo of a rectangular box is a trifle, but the rest is hard, you need to know the formulas.

To begin with, let's define the form, for this we first find out what they exist.

What shape can the box have?

  • Rectangle;
  • cylinder;
  • Truncated pyramid (very rare).

Then comes the measurements

Before calculating the volume of the box, we will measure it, but remember, the more accurate the measurements are made, the easier it is for you. "How to calculate the volume of a box?" - what to do next: determine what shape it is (cube or rectangle), dimensions.

What does knowledge of volume give us?

Knowing the volume of the box will not allow misunderstandings when loading goods into any type of transport that may be. Almost nothing depends on the volume of the box, rather, on the contrary, everything depends on the size of the product itself.

And why? Everything is obvious here, before you buy a box, you need to find out the size of the cargo that you are going to transport across the border.

Well, now you know the dimensions of the cargo, now it remains to calculate its volume (in order to purchase a box).

So, in order to find out how to calculate the volume of cargo in m3, the formula will be required first. How to calculate the volume of cargo in m3, the formula will help without a doubt in this matter, this is how it looks like V = a * b * h, everything is very simple.
