ABSTRACT
Problem 1. A water tank is the shape of a rectangular prism having length 2 m, breadth 75 cm and height 50 cm. Determine the capacity of the tank in (a) m3 (b) cm3
(c) litres.
Volume of rectangular prism= l× b× h (see Table 24.1) (a) Volume of tank= 2× 0.75× 0.5= 0.75 m3
(b) 1 m3 = 106 cm3, hence 0.75 m3 = 0.75× 106 cm3
= 750 000 cm3 (c) 1 litre= 1000 cm3, hence
750 000 cm3 = 750 000 1000
litres= 750 litres
Problem 2. Find the volume and total surface area of a cylinder of length 15 cm and diameter 8 cm.
