# How to work out numbers of bricks for given room

This construction video tutorial will provide useful guidance on computing number of bricks for a specified room.

To start, you have to find out dimensions first.

Here, internal length and breadth are taken as 3 meters. External length and breadth are taken as 3.4 meters.

Wall thickness is taken as .2 meters and depth is taken as 3 meters.

In the room there are 2 windows and 1 door with lintels.

At first you have to calculate the total area of the room and deduct the areas of door, windows and lintels. Then, you have to find out the volumes.

Given below, the dimensions of the windows, door and lintels :-

Brick Size = 0.2m x 0.1m x 0.1m

Door Size = 1.2m x 2m

Door Lintel Size = 1.4m x 0.1m

Window Size = 1.2m x 1.5m

Window Lintel Size = 1.4m x 0.1m

Wall Thickness = 0.2m

The following formulas will be used to calculate the numbers of bricks:

Brickwork Area – Deduction Area

Volume of brickwork = total brickwork area x wall thickness

Volume of single brick = Length x Breadth x Depth

To get the complete process, watch the following video.
