Answer:
Step-by-step explanation:
Given,
Size of one brick = 25cm × 10cm × 8cm Dimensions of wall = 5m × 3m × 16cm = 500 cm × 300 cm × 16cm
We know that,
Number of bricks required to build a wall = volume of wall / volume of one brick = (500×300×16) / (25×10×8) = 1200 bricks
∴ 1200 bricks are required to build the wall.

Answer:
1200
volume of 1 brick = l*b*h
= 25*10*8
= 2000 cm^3
volume of wall = l*b*h
= 500cm*300cm*16cm
= 2400000 cm^3
no.of bricks = volume of wall / volume of 1 brick
= 2400000 / 2000
= 1200
hence proved
