Question

A cylindrical bucket 28 cm in diameter and 72 cm high is full of water. The water is emptied into a rectangular tank 66 cm long and 28 cm wide. Find the height of the water level in the tank.

Answer 1

Let h be the height of rectangular tank = volume of cylindrical bucket

`66 xx 28 xx h = pi (28/2)^2 xx 72`

`66 xx 28 xx h = 22/7 xx 14^2 xx 14 xx 72`

                  `h  =(22 xx 2 xx 14 xx 72)/(66 xx 28)`

                  ` h = 24cm`

Hence, the height of rectangular tank is 24 cm.
