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.

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

Let the breadth of the tank be b m.

Volume of tank
= l x b x h
= (2.5 x b x 10) \({m}^{3}\)
= 25b \({m}^{3}\)

But, Capacity of tank = 50000 litres of water
\(\therefore \) 25b \({m}^{3}\)= 25000 b litres
\(\Rightarrow \) 25000 b = 50000
\(\Rightarrow \) b = 20 m.

Therefore, the breadth of the tank is 2 m.
