# QUANTITY OF BRICKS CALCULATION

The Quantity of bricks calculation is very important because most of buildings are to be constructed with 75% of brickwork especially (In Asian countries). So it is very important for us to know how many bricks are required in a 1-meter cube volume.

After knowing the 1-meter cube volume we can calculate the remaining quantity very easily by just multiplying the 1-meter cube result by the desired volume.

The calculation is quite simple means how many numbers of bricks you will require to build your wall and others, but there are a few important considerations you must always consider when you are calculating the quantity.

**The width**of the wall which going to be built**.****The number**of openings in the wall**(doors, Windows, etc.)****Size or**which**Type**of the brick going to use.

Let’s take this example to understand it well.

**EXAMPLE:**

Suppose we have to construct the wall having a volume of **the 1-meter cube**, the size of brick is going to use is **190 mm ****×****90 mm ****×****90 mm** and mortar is **8 mm thick** with the ratio of 1: 4. So

**1.)** Calculate the number of **bricks**.

**2.)** The quantity of** cement**?

**3.)** The quantity of** sand**?

**GIVEN DATA:**

Volume (L x W x H) = **1 meter cube**.

Mortar thickness = **8 mm**.

Mortar Ratio = **1:4**

Size of brick = **190 mm **×**90 mm **×**90 mm****.** or (0.19 m x 0.09 m x 0.09 m).

Size of brick with mortar = **198 mm **×** 98 mm**×** 98 mm**. or (0.198 m x 0.098 m x 0.098 m).

## Quantity of bricks Formula

**SOLUTION:**

This calculation can take place in 2 steps.

**1. Step: (Bricks Calculation)**

- Volume of 1 brick = (0.19 m x 0.09 m x 0.09 m) =
**0.001539 meter cube**. - Volume of 1 brick with mortar = (0.198 m x 0.098 m x 0.098 m) =
**0.0019 meter cube**. - No of bricks in 1 cum = volume/volume of bricks with mortar = 1/0.0019 =
**526 Bricks**.

**2. Step: (Mortar Calculation) **

- The volume is covered by 526 bricks in 1 Cum Volume =
**(Bricks number x Volume of 1 brick)**. - 500 Bricks Volume = 526 x 0.001539 =
**0.81 meter cube**. - Volume =
**(Total volume – volume of bricks)**. - Mortar volume = 1 – 0.81 =
**0.19 meter cube**. (wet volume). - Dry Volume = 0.19 x 1.33 =
**0.2527 meter cube**(dry Volume). Where (1.33 is a constant)

CEMENT:

**Cement: = (dry volume x Ratio x Density of cement in 1 cum)/Sum of Ratio.**

= (0.2527 x 1 x 1440)/5

= 72.77 kg /50 <1 bag = 50 kg>

= **1.5 bags**

SAND:

**Sand: = (dry volume x Ratio x 35.3147)/Sum of Ratio.** (1 Cum = 35.3147 cubic feet.)

= (0.2527 x 4 x 35.3147)/5

=** 7.1 cubic feet**

**Conclusion:**

BRICKS = **526**

CEMENT = **1.5 bags.**

SAND = **7.1 cubic feet.**

**Note:** These ratios may change by changing the dimension of the mortar thickness or size of the bricks as well as the mortar ratios 1: 4, 1: 6 etc.

This quantity of bricks calculation is based on experience and some practical Knowledge. The exact quantity may be less or more.
