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?
Solution:
We can note that temporary shelter would be of cuboid shape.
Length of temporary shelter
m
Breadth of temporary shelter
m
Height of temporary shelter
m
Remember that we need tarpaulin only for the four sides and the top.
Therefore, tarpaulin required=Surface area of top + Surface area of 4 sides
