16. Atul has a gift place in a cuboidal box of dimension I, b and h. He want to cover the box nicely to
present it to his friend on his birthday. Instead of using same colour paper, he decided to use
different colour on the opposite faces of the box. Derive the formula for its surface area
experimentally
Step-by-step explanation:
A cuboidal shaped box have 6 faces.
As he plans to cover it with different colors.
Total surface area of cuboidal is = 2(lb+bh+lh)
For each color he must have a color paper of = lb + bh + lh.
Respectively.
