Question

How many bricks of length, breadth, and height 25 cm, 15 cm, 5 cm respectively will be required to build a wall 50 m long 6 m high and 1/2m wide ?

Answer 1

Answer:

80000 bricks

Step-by-step explanation:

Volume of a brick = 25 * 15 * 5 cm^3

= (25/100) * (15/100) * (5/100)  m^3

= (1/4) *(3/20) * (1/20)  m^3

= 3/1600 m^3

Volume of wall = 50 * 6 * (1/2) = 150 m^3

Number of bricks required = 150 / (3/1600)

= 150 * 1600 / 3

= 50 * 1600

= 80000
