Question

How many bricks each 25 cm long, 10 cm wide and 7.5 cm thick, will be required for a wall
15 m long, 2.5 m high and 1.25 m thick?​

Answer 1

Step-by-step explanation:

Volume of brick- 25×10×7.5= 1875 cubic cm.

volume of wall in cm= 15×100×2.5×100×1.25×100= 46875000 cubic cm

hence brick required = volume of wall/volume of brick

n= 46875000/1875= 25000

hence brick required are 25000
