Question

A wall of length 10 m was to be built across an open ground. The height of the wall is 4 m and thickness of the wall is 24 cm. If this wall is to be built up with bricks whose dimensions are 24 cm × 12cm × 8cm, how many bricks would be required.

Answer 1

We have,

Length of the wall

Height of the wall

Thickness of the wall

Dimension of the brick is

We need to find the number of bricks

Here,

Volume of the wall,

Dimensions of the brick are,

So, number of bricks in the wall,

As this is not an integer, we should take least integer greater than.

So, we need bricks to build the wall.
