Question

Carol needs to know wrapping paper Will be needed to cover the outside of the box she can Use the perimeter surface area or volume as measure

Answer 1

Given:

The length of the box is l = 5 inches.

The width of the box is w = 4 inches.

The height of the box is h = 3.5 inches.

The objective is to find the surface area of the box to cover with a wrapper.

Step-by-step explanation:

The general formula to find the surface area of the box is,

`\text{TSA}=2(lw+wh+lh)\text{ . . . . . . (1)}`

On plugging the given values in equation (1),

`\text{TSA}=2(5*4+4*3.5+5*3.5)`

On further solving the above equation,

`\begin{gathered} \text{TSA}=2(20+14+17.5) \\ =2(51.5) \\ =103in^2 \end{gathered}`

Hence, the required wrapping paper is 103 square inches.
