Question

A brick measures 20 cm x 10 cm x 3.5 cm. How many bricks will be required for
a wall of dimensions 25 m x 2 m x 0.35 m ?


​

Answer 1

Answer:

25,000 Bricks are required for building the wall.

Step-by-step explanation:

For Given Brick,

Lenght (l) = 20cm

Breadth (b) = 10cm

Height (h) = 3.5cm

For Given Wall,

Lenght (L) = 25m = 2500cm

Breadth (B) = 2m = 200cm

Height (H) = 0.35m = 35cm

$No. \: of \: Bricks \: required \: = \frac{Volumne \: of \: Wall }{Volumne \: of \: a \: brick} \\ = \frac{L \times B \times H}{l \times b \times h} \: \\ = \frac{2500 \times 200 \times 35}{20 \times 10 \times 3.5} \\ = \frac{2500}{0.1} \\ = \frac{25000}{1} \\ = 25000$

Hope this will help you!!
