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. Similarly, you can calculate the volume of any rectangular parallelepiped, even a matchbox, even a refrigerator.

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

  • If the room has niches, ledges, or it itself is of a complex shape, then the task becomes more complicated. 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 shape, 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 only suit you if this thing is not afraid of water and you have a bath of the 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 take a full bath of water, immerse an object in it, collect all the water that spills over the edges and measure its volume in any way possible. For example, using a measuring cup.


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

The question of how to calculate the cubic capacity of wood building materials worries many developers. In order not to overpay for excess production or get into a difficult situation when you have to stop construction due to a shortage of lumber, the correct method of counting timber is required.

Cubic capacity is the volume of the body occupied by it in space. This value is determined by the product of the length, width and height of a homogeneous array. As for wood, it can be round timber, boards and timber. The parameter of these types of building wood is calculated in cubic meters.

This issue can be approached from several angles. Each method for calculating the volume of wood largely depends on the type of lumber itself.

Calculation of cubic capacity of roundwood

To calculate the volume of small batches of round timber, there are tables that take into account the average diameter of the trunk of each tree, the length of the log. Detailed tables can be easily found on the Internet.

Approximate table of cubic capacity of roundwood m3

Barrel diameter, mmbarrel length
1m2 m3m4 m5 m6 m8 m
140 0,016 0,0349 0,052 0,073 0,097 0,123 0,179
200 0,032 0,069 0,087 0,147 0,192 0,229 0,329
300 0,077 0,165 0,25 0,33 0,419 0,519 0,56
340 0,1 0,209 0,319 0,429 0,539 0,659 0,92
400 0,14 0,278 0,428 0,577 0,74 0,9 1,25
480 0,189 0,408 0,618 0,84 1,06 1,29 1,78

It is convenient to use such a table when evaluating several logs. When calculating the volume of a large amount of forest, they go the other way. Round timber is stored in the most dense arrays.

Proceed as follows:

  1. Wood is sorted by length. Two-meter woods are folded into a separate herd. Longer logs are grouped in another stack.
  2. The trunks are laid, alternately orienting the bases and tops of the round timber in different directions. This allows you to get the most dense stack of logs.
  3. Individual chocks are laid out in one line along the length of the stack.
  4. An array of wood must be stored in a shape as close as possible to a regular parallelepiped.
  5. The product of the width, length and height of the stack will determine the storage cubic capacity of the round timber.
  6. The result obtained is multiplied by the correction factor. So, for woods up to 2 meters k = 0.56, and for longer logs k = 0.5.

This method of determining the volume of round timber is closest to the actual volume of wood. All the intricacies of calculating this parameter are perfectly mastered by employees of timber warehouses. Without experience in this area, an independent calculation may not be in favor of the buyer.

Calculation of the cubature of boards and their number

The basic unit of calculation for lumber is 1 m3. Determining the cubic capacity of a stacked edged board is quite simple. Lumber of the same type and size is stacked tightly in piles. It is enough to measure the length, width and height of the parallelepiped in meters, and then multiply them. The result obtained will be the actual value of the volume of trimmed material.

It is important for the developer to know how many units of products of a certain size fit in 1 m3. In some cases, the lumber supplier attaches a trade card on each package of boards indicating the characteristics of wood, volume, price per 1 m3 of products, as well as the number of boards in a stack.

Independent calculation

You can independently determine the number of pieces of boards. To do this, you need to measure the stack and calculate the volume of the package. Knowing the dimensions of lumber, determine the volume of a unit of production. The quotient of dividing these two parameters will give the real number of pieces of boards.

For example, a board has dimensions of 200 x 30 x 6000 mm. Therefore, the volume of lumber will be equal to 0.036 m3. It will fit in 1 m3 - 1 / 0.036 \u003d 28 pcs.

Tabular method

In order not to mess with measurements and calculations, you can use tables. For edged material 6 meters long, the table will look something like this:


For unedged boards, indicative tables are used - taking into account the variable width along the entire length of the unit of production. The calculation of the volume of wood is carried out according to the same methodology as the calculation of the volume of edged material, with the introduction of a correction factor k in the range from 0.6 to 0.8. The value of the coefficient depends on the degree of curvature and the thickness of the bark.

The table of volumes of unedged timber 6 m long with conditional k = 0.7 will be as follows:

Calculation of the cubic capacity of the timber and its quantity

Manual way

The beam is a parallelepiped with almost even edges. The manual method for determining the cubature of timber and the number of units of wood in 1 m3 is acceptable for small batches of goods. It is performed in the same way as the calculation of the edged board.

Tabular method

In order to avoid time costs when supplying a large number of wooden products, tables are used to determine volume indicators. With a standard beam length of 6 m, the tabular data will be as follows:

Online calculation of the number of boards and timber per 1 m3

Before purchasing any building material, it is necessary to determine the right amount as accurately as possible, otherwise you can lose some amount due to the remaining surplus or the need for additional purchases, as well as the unaccounted for possibility of fraud by unscrupulous sellers. Timber, logs, boards and similar wood products, as you know, are sold in cubic meters, which means that you need to know in all subtleties the calculations for determining the volume of these materials, as well as converting the required number of pieces into cubes and back. And in the case of purchasing timber for building a house, when calculating the required amount of this building material, it is also necessary to take into account the design and features of the future building.

Basic calculations - volume determination and conversion from pieces to cubes and vice versa

Calculating the cubic capacity of timber, boards and similar lumber is very simple. To do this, you need to know the thickness, width (height) and length of the product. And, as you know from a school textbook on geometry, you need to multiply these dimensions:

V = T ∙ H ∙ L, where

V is the volume of timber, m 3;

T is the thickness;

H - width;

L is the length.

Before calculating, dimensions should be given in one unit of measurement: mm, cm or m. It is better in meters, so that later you do not have to convert from mm 3 or cm 3 to m 3.

Beam size chart

For example, let's calculate the cubic capacity of a bar 150x200. These dimensions, as you know, are indicated in mm. That is, the thickness of the product is 0.15 m, and the width is 0.2 m. The standard length of timber and boards is 6 m (sometimes also indicated in mm - 6000). Or maybe another. But for example, let's take exactly 6 m. Then the volume of this lumber:

0.15 ∙ 0.2 ∙ 6 \u003d 0.18 m 3.

Now you can convert the required amount (in pieces) of this product into cubes. Let's say you need 49 pieces:

0.18 ∙ 49 \u003d 8.82 m 3.

Knowing the volume of one product, you can also calculate the cube of the timber, that is, determine how many of its units (pieces) are in 1 m 3. To do this, you need to divide 1 cube by the cubic capacity of one product already calculated or taken from the reference tables (in this example, 0.18 m 3):

1 / 0.18 \u003d 5.55555 ... pcs.

In the same way, the amount of this type of timber is calculated for any volume.

The nuances of calculations - how not to make mistakes and not let yourself be deceived

As follows from the above methodology and calculation examples, it is very easy to calculate the required volume of timber in pieces or cubic meters. However, it must always be remembered that in 1 cubic meter there is not an integer number of these products. For the example given in the example with dimensions of 150x200 and a length of 6 m - 5.55555 ... pcs. Unscrupulous, most often retailers of timber cleverly take advantage of this.

For example, you need 1 cube of this material from the example. The seller, of course, releases 5 products, but takes the amount as for a whole cube. The overpayment will be the cost of half a beam.

And let's say that the same 49 bars from the example are needed to build a house. And if the seller considers according to the following scheme, then you will have to significantly overpay for the timber received:

  • 1 cube - 5 products 150x200 6 m long;
  • 49/5 = 9.8 cubes payable.

This is a divorce of the purest water for 5 units of timber. They are superfluous and not needed, however, they will be paid, but not received. Above, in the calculation examples, the data of 49 products have already been translated into cubes - this is 8.82 m 3. That is, a "particularly enterprising" seller will deceive an inattentive buyer by:

9.8 - 8.82 \u003d 0.98 m 3 timber,

which is 0.98 / 0.18 \u003d 5.44444 ... pcs. this lumber (0.18 - the volume of one product calculated above).

Therefore, it would be most correct to calculate in advance exactly the number of units (pieces) of the material, and only then, using these data and the dimensions of the timber or board, calculate their actual cubic capacity.

That is, in the case of purchasing one cubic meter in the above example, you must first decide how many bars you really need to take - 5 or 6. And then we consider their cubic capacity:

0.15 ∙ 0.2 ∙ 6 ∙ 5 (or 6 pcs.) \u003d 0.9 (or 1.08) m 3.

And for 49 units of this timber:

0.15 ∙ 0.2 ∙ 6 ∙ 49 \u003d 8.82 m 3.

Then you will have to pay exactly for these 0.9 (1.08) or 8.82 cubic meters, having received exactly 5 (6) or 49 products. Moreover, both the quantity in pieces and the volume in m 3 must be indicated in the invoice for the timber sold by the seller.

Other features of calculating the cubature of lumber

Another important feature that you should know for the correct calculation of the cubic capacity of timber or boards when purchasing them. The actual length of lumber usually always slightly exceeds the standard or declared by the manufacturer of this product. So, instead of 6 m, the average length of the considered timber, as a rule, is 6.05 m. This is due to the fact that the ends of the lumber are not processed after it has been cut, because of which they may turn out to be uneven, go at angles, and be different or simply be dirty. Of course, these 5 cm do not need to be paid. But some cunning sellers, although quite rarely, still try to take into account even this when calculating cubic meters, which is pure deception.

And regarding the calculations for grooved and profiled timber. The presence of spikes, grooves, and other protruding or turned places should not be embarrassing. The calculation of the cubic capacity of such materials is no different from determining the volume of ordinary products that are even on all sides. For grooved and profiled lumber, the rule applies that only the main part (working width) of the product is measured and taken into account, and all structurally necessary and / or decorative elements are not taken into account in the calculations. This provision applies to absolutely all types of timber.

Purchase of large volumes of materials - calculation of storage and dense cubic meters

When it is necessary to purchase a large amount of timber, their cubic capacity is calculated somewhat differently than discussed above. For example, a timber and a board are needed for the construction of an impressive spacious house, as well as various other outbuildings near it. In this case, the necessary lumber, for sure, will be of different sizes in cross section and length. To measure and calculate each type of required material with similar purchase volumes is an occupation that can take more than one day.

For such cases, there is a specific calculation method. It is based on two important concepts:

  1. 1. Dense cubic meter of wood. This is the name of the volume occupied only by wood and not having voids in it, as well as gaps. It is determined by measuring individual timber pieces, and then subsequent calculation of their total cubic capacity.
  2. 2. Folding cubic meter. This is the name of the volume occupied by the lumber stacked as tightly as possible and having voids, as well as gaps between individual wood products. It is determined by measuring the stack, and then multiplying the dimensions of the latter. Moreover, in such a package, the main amount of material should have approximately the same length, and the remaining products may be shorter, but not longer. It is allowed to have short sawn timber in piles, which should be tightly stacked one after another.

In order to quickly calculate the large volume of required purchased lumber, which is already prepared and stored in the form of a stack, the latter is first measured, and then its cubic capacity is calculated. This will calculate the folding cubature. Then its value must be multiplied by a special conversion factor. The result will be the volume of only wood (a dense cubic meter), that is, exactly those materials that are bought and will be paid for.

The value of the conversion factor is regulated by a number of standards for lumber: GOST 6782.2-75, 6782.1-75, 6564-84, OST 13-24-86 and others. For timber and boards, depending on their moisture content and the type of wood from which they are made, it is in the range of 0.74–0.82.

We consider the required cubic capacity of timber for building a house

  • The height of the outer walls, measured from the level of the foundation. Let's denote it as H.
  • The height of the internal partition walls, if any, and should be made of timber.
  • The length of the outer and inner walls.
  • The number and length of the beams used in the truss system, as floor beams and, as well as in its other structures - if provided for by the project.

Then we select the thickness of the material for each of the above structural elements. For external and internal load-bearing walls, depending on the purpose of the house being built and the region where it is being built. For non-bearing partitions - at your own discretion. The plinth (lowest) crown of the outer walls is usually slightly thicker than the rest of the timber for them. For the remaining elements of the structure, the thickness of the material is selected based on the conditions of its operation, as well as the required strength of the structures in which it is used. In a well-designed project, by the way, the thickness of the beam used for walls, the basement crown, and other building structures should already be indicated.

Now only pure arithmetic remains. First, we calculate the perimeter of the house - we add up the length of all its external wall structures. For a simple rectangular or square structure, you just need to add up its width and length, and multiply the resulting value by 2. Then we calculate the cubature of the base crown:

V C = T C ∙ Z C ∙ I, where

V C - total cubic capacity of basement lumber, m 3;

T C - thickness of the basement, m;

Z C - its width (height), m;

I - the perimeter of the outer walls, m.

Calculate the remaining height of the outer walls, m:

h \u003d H - Z Ts, where

H - total height, m.

We calculate the area of ​​​​external wall structures without a basement crown, m 2:

If the thickness of the material of the basement crown is the same as that of the entire wall, then the area of ​​\u200b\u200bthe latter, m 2:

We calculate the area of ​​\u200b\u200bthe inner walls, the thickness of the lumber in which is the same as that of the outer ones, m 2:

S В1 = H В ∙ L В1 , where

H B - the height of the internal walls, m;

L B1 - the total (total) length of the internal walls, the material thickness of which is the same as that of the external ones, m.

We calculate the area of ​​\u200b\u200bthe internal walls, the thickness of the timber in which is different, m 2:

S B2 = H B ∙ L B2 , where

L B2 - the total length of the internal walls, the material thickness of which is different, m.

We calculate the cubature of the main lumber - for external walls and internal partitions from the same timber, m 3:

V S = (S Н + S В1) ∙ Z S , where

Z S - selected thickness of the product, m.

We determine the volume of material for internal partitions from another timber, m 3:

V B = S B2 ∙ Z B, where

Z B - selected material thickness for these partitions, m.

The results obtained (V C, V S and V B) are divided by the length of the purchased lumber and its selected width (height). Get the amount of material in pieces. We round this value to an integer value, and then we recalculate V Ts, V S and V V, as described in the second chapter.

To save on lumber, you should calculate the total areas of window, door and other openings for the corresponding walls. Then their values ​​\u200b\u200bshould be subtracted from S H, S B1 and S B2, respectively. After that, we calculate V S and V B using the same formulas. Then we increase the obtained values ​​​​by 10-20% - so that there is a margin just in case.

The cubic capacity of the timber for the rest of the elements of the house in which it is used is calculated even more simply. Its total length is calculated, which we multiply by the thickness and width selected for the material.

When carrying out construction work on the construction of a residential building, a specialist needs to perform a large number of various tasks, some of which are: drawing up and calculating the estimated cost before the final finishing of the premises of a residential building. It is mandatory to calculate the required amount of various building materials, which is quite difficult to do. Therefore, such knowledge - how many boards are in a cube, is very important for a specialist who is engaged in the construction of a residential building and wants to do the job as efficiently as possible and quickly in time.

Buyer's club: existing types of boards

To calculate exactly how many pieces of a board are in a cube, you will need to know not only what exactly the cube of the board means, but it is worth understanding the important point that there are different types of boards and what is possible to purchase on the modern market to perform a variety of construction work. It should be noted that the cube of almost all materials, regardless of the type of material, is calculated in the same way, that is, according to one specific method. The types of boards have no influence on the calculation of the cubic capacity of this building material.

The non-grooved type of lumber is: timber, various edged boards, as well as unedged boards (they are an exception when calculating cubic capacity, because this process is a little different). Grooved types (which have special grooves for the joint) include: modern lining, blockhouse, flooring material, as well as imitation of natural timber. When you choose to buy a tongue-and-groove type of building material, then you need to pay attention to the fact that when making a calculation, only the working width of the board without a spike is used. If we talk about a blockhouse (imitation of a log), then when calculating the cubic capacity, only the thickness at its highest point is taken.

How many boards are in 1 cube: performing a calculation

Any person, since his school days, understands how the calculation of cubic capacity is made. For this procedure, it is necessary to calculate quantities such as: length, width and height. A similar principle is also used to calculate the cubature of 1 board. It is recommended that when performing such calculations, convert all available values ​​​​in meters. Cubic capacity of 1 board, which has a section of 150x20 mm. and a length of 6 m., is calculated as follows: 0.15 is multiplied by 0.02 and by 6, so that the cubic capacity of this board will be 0.018 cubic meters.

Apply the volume formula V= L*h*b (where L is the length, h is the height, b is the width).

L=6.0; h=0.02; b=0.15.

Thus, V \u003d 6.0 * 0.02 * 0.15 \u003d 0.018 m 3.

To determine how many boards are in one cube: 1 m 3 is divided by the cubic capacity (the volume of one board).

1 m 3 / V = ​​N pcs.

1 m 3 / 0.018 m 3 \u003d 55.55 pcs.

Thus, the number of boards in one cube is 55.5 pieces.

It is quite easy to find out the cost of a certain type of board when its volume values ​​\u200b\u200bare known: 0.018 is multiplied by the price of 1 cubic meter. When 1 cube of a certain type of board has, for example, a cost of 5500 rubles, then the cost will be 99 rubles. At this point in the calculation, there is some trick of sellers and managers in hardware stores, because the cubic capacity of the material is rounded up to some integer values.

Such rounding can lead to such a moment that the price of 1 board (when 1 cube costs 5500) will be completely different values. In addition to all this, it should be noted that for various boards for construction, which make up a nominal length of 6 meters, in fact, the length is 6.1 - 6.2 m, which is not taken into account when selling this building material. This also applies to the acquisition of a significant number of boards. This is quite clearly visible if, for example, a 150x20 mm board is used. The number of boards in a cube is a value of 55.5 pieces. But, in a cube, 55 pieces are considered, which, when calculating, will have a value of 0.99 cubic meters. In fact, it follows from this that the overpayment for 1 cubic meter of this popular building material can be 1% of the real price. For example, 5500 instead of 4995 rubles.

To calculate the cubature for a non-cut-off type of board, slightly different methods are used. When it comes to buying 1 board, then measuring its thickness, as well as the total length, is done in the same way as when choosing a cut building material. In this case, the width for calculations is taken as an average - between a large value and a small one.

For example, when the width of the board at the end is 25 cm, and at the other 20, then the average value will be approximately 22 centimeters. When it is necessary to calculate the volume of a significant number of such boards for construction, then it will be necessary to decompose them so that the wide one does not differ from the narrow one, more than 10 cm. The main length of this material in the unfolded stack should be approximately the same. After that, using a conventional tape measure, an accurate measurement of the height of the entire stack of boards is made, the width is measured (approximately in the middle). The result obtained will then need to be multiplied by a special coefficient ranging from 0.07 to 0.09, in direct proportion to the existing air gap.

How many boards in 1 cube: special tables

To calculate exactly what number of boards of a certain width, length in 1 cubic meter, various tables are used. Below are several such specialized tables, which indicate the cubature of the common and popular types of this material today. It is possible to calculate the volume of various boards having different sizes, for example, material for erecting a fence on your site, using the available formula, which is presented above.
