Answer 1

Given:-

length, l=16in

width, b=13in

thickness, t=3in

To Find:-

Area of wrapping paper required.

Explanation:-

Since, wrapping paper is to be wrapped over the whole rectangular box.Therefore, we have to calculate the total surface area of the rectangular box.

$TSA=2\times\left(lb+bt+lt\right)\\TSA=2\times\left((16\times13)+(13\times3)+(16\times3)\right)=590in^{2}$

Therefore, 590$in^{2}$ of paper is required to wrap the whole rectangular box.

Answer 2
