A soft drink is available in two packs – (i) a tin can with a rectangular base of length 5 cm and width 4 cm, having a height of 15 cm and (ii) a plastic cylinder with circular base of diameter 7 cm and height 10 cm. Which container has greater capacity and by how much?
Rectangular can: l = 5 cm, b = 4 cm, h = 15 cm
Volume of cubcoid = l X b X h
= 5 X 4 X 15 = 300 cubic cm
Cylindrical can: r = 35 cm, h = 10 cm
Volume of cylinder = π r2 h
= (22/7) X 352 X 10
= 385 cubic cm
Difference = 385 – 300 = 85 cubic cm
