Problem
A water tank is constructed by welding a right circular cylinder vertically on the top face of a cuboidal base. The inner dimensions are as follows:
• Cuboidal part: 1.2m×1.0m×0.4m
• Cylindrical part: internal radius 0.5m, height 2m
Assume the tank is completely filled with water.
(i) Calculate the volume of the cuboidal portion.
(ii) Calculate the volume of the cylindrical portion.
(iii) Find the total capacity of the tank in litres. (Use 1L=1000cm3.)
