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

Explanation

Total number of bricks = `(Volume of wall / Volume of bricks)`

Length of wall = 10m=`10xx100`=`1000 cm`

Breadth of wall = `24 cm` and height of wall = `4m`=`4xx100 cm`
Volume of wall= Length x breadth x height

`1000xx24xx400 cm^3`

For Brick

length=`24 cm`

breadth=`12 cm`

height= `8 cm`
