Question

The capacity of a cuboidal tank is 50000 litres of water. Find the breadth of the tank, if its length and depth are respectively 2.5 m and 10 m.

Answer 1

Let the breadth of the tank be b m.

Length (l) and depth (h) of tank is 2.5 m and 10 m respectively.

Volume of tank = l × b × h

                       = (2.5 × b × 10) m³

                       = 25b m³

Capacity of tank = 25b m³ = 25000 b litres

∴ 25000 b = 50000

⇒ b = 2

Therefore, the breadth of the tank is 2 m.
