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 βnβ cuboidal tanks having dimension 12 cm Γ 5 cm Γ 11 cm, each. Find the value of βnβ.Solution
Radius of the base of the cylindrical drum = 28/2 = 14 cm According to the question, Volume of cylindrical drum = volume of βnβ cuboidal tanks Therefore, (22/7) Γ 14 Γ 14 Γ 15 = n Γ 12 Γ 5 Γ 11 Or, n = 9240/660 = 14
