Question
A cubical box has each edge of length 10 cm and another cuboidal box is 12.5 cm long, 10 cm wide and 8 cm high. Find the volume of the box which has greater lateral surface area.
Solution
Lateral surface area of cubical box = 4a2 = 4(10)2 = 400 cm2Lateral surface area of the cuboidal box = 2(l + b)h = 2(12.5 + 10)8 = 360 cm2
Clearly, the cubical box has greater lateral surface area.
∴ Volume of the cubical box = a3
= 103
= 1000 cm3

Parveen wanted to make a temporary shelter for her car, by making a box-like structure with tarpaulin that covers all the four sides and the top of the car (with the front face as a flap which can be rolled up). Assuming that the stitching margins are very small, and therefore negligible, how much tarpaulin would be required to make the shelter of height 2.5 m, with base dimensions 4 m × 3 m?
