Question

2)
bricks of length 25cm, breadth 15 cm and
height 10cm
required to build a wall of
length 6m. height 2.5m and breadth 0.5m. A​

Answer 1

Answer:

2000 bricks are required.

Step-by-step explanation:

Length of wall, L = 6 m = 600 cm

Breadth of wall, B = 0.5 m = 50 cm

Height of wall, H = 2.5 m = 250 cm

Length of brick, l = 25 cm

Breadth of brick, b = 15 cm

Height of brick, h = 10 cm

Volume of wall = L × B × H = 600 × 50 × 250 cm³

Volume of brick = l × b × h = 25 × 15 × 10 cm³

Bricks required = Volume of wall / Volume of brick

$= \frac{600 \times 50 \times 250}{25 \times 15 \times 10} \\ = \frac{600 \times 2 \times 25}{15} \\ = \frac{200 \times 2 \times 25}{5} \\ = \frac{200 \times 2 \times 5}{1} = 2000$
