Question

The surface area of a cube is 328.56 square inches. How long are it’s sides?

Answer 1

Answer:

7.4 in

Step-by-step explanation:

Surface area of a cube = 6s²

(where s is the side length)

Given:

• SA = 328.56 in²

Substituting the given value into the formula and solving for s:

⇒ 328.56 = 6s²

⇒ 328.56 ÷ 6 = 6s² ÷ 6

⇒ 54.76 = s²

⇒ s = √54.76

⇒ s = 7.4 in

Answer 2

TSA of a cube=328.56

Side be x

• 6x²=328.56
• x²=54.76
• x=√54.76
• x=7.4in
