Question

Jen made a small box out of cardboard to wrap a birthday present. The box is 4 in. high, 4.4 in. long, and 5 in. wide. She wants to know the how much wrapping paper she will need to wrap the box. Find the surface area of the box.

A: 75.2 in.2
B: 119.2 in.2
C: 88.0 in.2
D: 59.6 in.2

Answer 1

the correct option is B

Answer 2

Option B.
`119.2\ in^(2)`

Explanation:

we know that

The surface area of the box is equal to

`SA=2B+Ph`

where

B is the area of the base of the box

P is the perimeter of the base of the box

h is the height of the box

Find the area of the base B

`B=4.4*5=22\ in^(2)`

Find the perimeter of the base P

`P=2(4.4+5)=18.8\ in`

The height is
`h=4\ in`

substitute the values

`SA=2(22)+18.8(4)=119.2\ in^(2)`
