How many bricks, each of size 25 cm x 13.5 cm x 6 cm, will be required to build a wall 8 m long, 5.4 m high and 33 cm thick?
We know that,
Volume of cuboid = Length × Breadth × Height
Firstly,
Volume of the brick = 25 × 13.5 × 6
= 2025 cm3
Now,
Volume of the wall = 800 × 540 × 33
= 14256000 cm3
Hence,
Total number of bricks required =
=
= 7040 bricks
