Answer 2

Answer:

2000 bricks

Step-by-step explanation:

i) For a wall (cuboidal) : Length (L) = 6m = 6 × 100 = 600 cn

Height (H) = 2.5m = 2 × 100 = 250 cm

Breadth (B) = 0.5m = 0.5 × 100 = 50cm

∴ Volume of wall = L × B × H

= (600 × 50 × 250) c.c.

ii) For a brick (cuboidal) : length (l) = 25cm

breadth (b) = 15cm

height (h) = 10cm

∴ Volume of brick = l × b × h

= (25 × 15 × 10) c.c.

iii) Number of bricks required to build a wall :-

=> $\dfrac{\text{Volume\:of\:wall}}{\text{Volume\:of\:one\:brick}}$

=> $\dfrac{\tt{600 \times 50 \times 250}}{\tt{25 \times 15 \times 10}}$

=> 2000

∴ Number of bricks required to build a wall = 2000
