Question

A wall 9 m long, 6 m high and 20 cm thick, is to be constructed using bricks of dimensions 30 cm, 15 cm and 10 cm. How many bricks will be required ?

KnowledgeBoat · Accepted Answer

Given: The length of the wall = 9 m. The height of the wall = 6 m. The breadth of the wall = 20 cm = 0.2 m. As we know that volume of wall = length x breadth x height = 9 x 6 x 0.2 m³ = 10.8 m³ The length of the brick = 30 cm = 0.3 m. The breadth of the brick = 15 cm = 0.15 m. The height of the brick = 10 cm = 0.1 m. As we know that volume of one brick = length x breadth x height = 0.3 x 0.15 x 0.1 m³ = 0.0045 m³ Let a be the number of bricks. Number of bricks = ⇒ a = ⇒ a = ⇒ a = 2400 Hence, the number of bricks required to construct the wall is 2400.
