Answer 1

We're finding how much surface he needs in order to entirely wrap the box, so let's use the surface area form to find it.


`SA: A_1 + A_2 + A_3`


`A_1 = 2(5 \cdot 3)` (front and back)

`A_2 = 2(3 \cdot 14)` (two sides)

`A_3 = 2(5 \cdot 14)` (top and bottom)

Hence, our SA becomes
`2(5 \cdot 3) + 2(3 \cdot 14) + 2(5 \cdot 14)`

`= 254 ft^(2)` of wrapping paper.

Answer 2

you're going to need about an 8 feet tall 19 feet wide wrapping paper.
