Question

The length, breadth, and height of a cuboidal water tank are 7m, 6m and 15m, respectively. If 8400 litres of water is pumped out of the water tank, find the fall in the water level in the water tank.

Answer 1

Height of the water tank = 6 m (Given)

Convert litres to m

1 litre = 0.001 m³

8400 litres = 8.4 m³

Find the height of the water that was pumped out:

Volume = Length x Breadth x height

8.4 = 7 x 6 x height

8.4 = 42 x height

height = 8.4 ÷ 42 = 0.2 m

Answer: The water level fell by 0.2 m
