Question 6.

A trolly is full of bricks. Length of the trolly is 400 cm, breadth is 200 cm and height is 100 cm. Length, breadth and height of a brick are 20 cm, 10 cm and 6 cm respectively. How many bricks are there in the trolly?

Solution:

Length of trolly, L = 400 cm

Breadth of trolly B = 200 cm

Height of trolly, H = 100 cm

Volume of trolly = L × B × H

= 400 cm × 200 cm × 100 cm.

Length of a brick, l = 20 cm

Breadth of a brick; b = 10 cm

Height of a brick, h = 6 cm

Volume of a brick = 20 cm × 10 cm × 6 cm

Number of bricks in the trolly

= \(\frac{\text { Volume of trolly }}{\text { Volume of each brick }}\)

= \(\frac{400 \times 200 \times 100}{20 \times 10 \times 6}\)

= \(\frac{20 \times 20 \times 50}{3}\) = \(\frac{20000}{3}\)

= 6666 (Approx)
