Question

The length of a balcony is 20 m and breadth 18 m.If it is to be with bricks of length 22.5 cm and breadth 10 cm.Find the number of bricks required

Answer 1

Length of balcony = 20m

breadth = 18m

area = l*b

= 20*18

= 360 m^2

Length of bricks = 22.5cm =0.225m

breadth = 10cm = 0.1 m

Area = l*b

= 0.225*0.1

= 0.0225 m^2

no. of bricks required = 360/0.0225

= 16000 bricks are required Ans
