Question
The diameter of the base of a cylindrical drum is 28 cm
and its height is 15 cm. The drum is full of water and the water from the drum is transferred to ‘n’ cuboidal tanks having dimension 10.5 cm × 10 cm × 11 cm, each. Find the value of ‘n’.Solution
Radius of the base of the cylindrical drum = 28/2 = 14 cm According to the question, Volume of cylindrical drum = volume of ‘n’ cuboidal tanks Therefore, (22/7) × 14 × 14 × 15 = n × 10.5 × 10 × 11 Or, n = 9240/1155 = 8
