Answer:
39.5 cm²
Step-by-step explanation:
Given,
Length of the match box l = 4 cm
Breadth of the match box b = 2.5 cm
Height of match box h = 1.5 cm
It's outer sides are to be covered exactly with craft paper.
For the amount of paper required to cover the match box we need to calculate the surface area of the match box.
Thus,
Surface area of the match box = 2(lb + bh + lh)
=> 2(4 * 2.5 + 2.5 * 1.5 + 4 * 1.5)
=> 2(10 + 3.75 + 6)
=> 39.5 cm^2
Therefore,
The amount of paper required = 39.5 cm²
Hope it helps!
