A cube and the net for the cube are shown. What is the surface area of this cube?

A.30 cm² B.70 cm² C.125 cm² D.150 cm²

Answers

SA of Cube= D. 150 cm2
= 6S^2
= 6(5^2)
= 6(25)
= 150

From what I know I believe that D is the answer. Because the surface area of one side is 25, so there are 6 sides so do 25×6 and get 150cm².
