Question

The water level in a rectangular tank 65 cm long and 45 cm wide is 14 cm. It will take another 58.5 litres of water to fill the tank to its brim. Find the height of the tank.

• A. 24 cm
• B. 28 cm
• C. 34 cm
• D. 38 cm

Answer 1

The correct option is C 34 cm

Volume of water in the tank = 65 cm $\times$ 45 cm $\times$14 cm
= 40950 $c{m}^3$
= 40.95 litres
Capacity of the tank = 40.95 litres + 58.5 litres
= 99.45 litres
= 99450 $c{m}^3$
Height of the tank = $\left(\frac{99450}{65\times 45}\right)$
= 34 cm
The height of the tank is 34 cm.
