Answer 1

311.04 ft

Explanation:

i took the quiz. AND when you multiply 7.2 x 7.2 you get 51.84, then multiply that by 6 (because a cube has 6 sides) and you get 311.04 hope this helped. :)

Answer 2

The surface area of a cube is:

A=6s^2 (It is just the area of 6 sides (squares) all having an area of s^2)

A=7.2^3=373.248 ft^3
