Answer:
D) 220 sq in
Step-by-step explanation:
Because this question is asking for the amount of wrapping paper, we are looking for the surface area of this box because wrapping paper covers the outside, not inside of a package.
This box is a rectangular prism and the surface area formula is 2B + Ph.
B = area of one base
P = perimeter of one base
h = height of the prism (length of side connecting two bases)
B is 5(10)
= 50
P is 5 + 10 + 5 + 10
= 30
h is 4
Plug in dimensions and solve.
2(50) + 30(4)
100 + 120
220
