Do you know how many bricks are in the cube of masonry? Pay more!

What can we build a house?

The exclamation mark at the end of this sentence is only relevant in a well-known song. He is synonymous with the phrase " very simple ". And if the house is built real, not song? From real bricks, real timber, real cement, which have a real price? Then the song exclamation point will turn into a concerned question. And the emphasis will shift from the word " what " to the word " worth ". And the costs that are hidden behind this word are determined not only by the market of building materials, but also by our awareness in the affairs of construction.

Mathematics is an exact science, but the bricks are different, and therefore their number in one cube is different. Therefore, in order to calculate how many bricks are in the cube of the masonry, one should take into account:

- brick size ;

- type of masonry ;

- the thickness of the seams.

We begin to count by putting a tick in front of these three unknowns. And to make sure that one question about how many bricks in the cube of masonry, we can get several answers, let's compare this amount for different brick sizes.

Size, quantity in m ³

1 = 512/394

1.5 = 378/302

2 = 242/200

Note. The quantity designation is read as follows: "without laying / taking into account the masonry".

Note that in the formulation of the problem "how many bricks in the cube of masonry," an inaccuracy is admitted, which will lead to confusion in the calculations. In fact, no one will build a brick cube in the true sense of the word! There will be a house, a garage, something else, but not an ancient fortress, with walls a meter thick . The thickest wall covering today is two and a half bricks. And there are two, one and a half, one brick and half a brick. With these values determined, then we will assume, but not in cubes, but in square meters. Below are examples. But for what then it is necessary to know how many bricks in one cube of masonry, if the walls are measured in square meters? The logic is simple - we build in m ² , we buy in m ³ . So how to count? The algorithm is approximately as follows:

1) find out the total area:

A) external walls;

B) inside walls;

2) determine the size of the brick and the type of seam in the masonry;

3) determine the width of the masonry:

A) external walls;

B) internal walls;

4) calculate the number of bricks separately:

A) for external walls;

B) for the internal;

5) output the total number;

6) divide the figure obtained by the already known number of bricks in the cube;

7) with the result we go to the store - this is the right number of brick cubes.

If you want, you can add one more item - "multiply by the price of one cube", in order to know how much money to take. And you need to take with a margin for an additional 15% of the bricks that make up the fight and marriage. We have already mentioned how many bricks are in the cube of masonry. Here are some figures for a square meter. This is incomplete information, just show for comparison how the amount of bricks varies depending on its size and accounting / non-accounting of the seam. When calculating these nuances should be taken into account.

Example 1. For the same masonry in 1 brick for different sizes:

Size - quantity (excluding / including seams)

1 = 128/102

1.5 = 95/78

2 = 60/52

Example 2. For different clutches with one brick size (1):

Type of masonry - number (excluding / including joints)

0.5 = 61/51

1 = 128/102

1.5 = 189/153

As you can see, the larger the size, the smaller the quantity, but the price will be higher. So the losses due to inaccurate calculations are significant. Minimize reattractions can be, not only all accurately calculating. If laying in two and a half bricks, then you can also use broken brick. There will be a solution overrun, but it's cheaper.

All considered, but the point to put early. For the construction requires more wood, more faithfully, materials from wood. Board, boards. So, it is necessary to calculate the number of bars in the cube. The following table is designed to facilitate this process.

Explanation of the table: the numbers in brackets indicate the volume of one Th unit of the beam.

Well, now you can sing the line with which you started the conversation, not with a question, but with an exclamation point!
