How many square feet of paper do you need to cover a cube with a side 10 in. long? round your answer to two decimal places. a. 6.94 sq ft b. 86.40 sq ft c. 4.17 sq ft d. 82.52 sq ft

Okay, so we basically need to find the surface area in feet.
1) 10 inches = 10/12 feet = 5/6 of a foot
2) To find the area of a side surface, we have to square the side: (5/6)^2 = 25/36
3) All right! We have six of those squares, so 6(25/36) = 150/36 = 4.166...
The closest to this is 4.17 square feet, so C is the answer.
Hope this helps!
