How many bricks, each of size 25 cm × 13.5cm × 6 cm, will be require

1.	How many bricks, each of size 25 cm × 13.5cm × 6 cm, will be required to build a wall 8 m long, 5.4 m high and 33cm thick?
Answer» We know that volume of cuboid = length × breadth × height Volume of the brick = 25 × 13.5 × 6 = 2025 cm³ Volume of the wall = 800 × 540 × 33= 14256000 cm³ Therefore, total number of bricks required =Volume of the wall/ volume of the each brick = 1425000/2025 = 7040 bricks

How many bricks, each of size 25 cm × 13.5cm × 6 cm, will be required to build a wall 8 m long, 5.4 m high and 33cm thick?

Answer»

We know that volume of cuboid = length × breadth × height

Volume of the brick = 25 × 13.5 × 6 = 2025 cm³

Volume of the wall = 800 × 540 × 33= 14256000 cm³

Therefore, total number of bricks required

=Volume of the wall/ volume of the each brick

= 1425000/2025

= 7040 bricks
