A.
1350 cm2

B.
900 cm2

C.
225 cm2

D.
3375 cm2

Answer 1

To find the surface area of the entire cube, you need to find the area of one of the faces and multiply it by 6 because a cube has 6 sides. To find the area of a square, you multiply 15 times 15 to get 225. Multiplying this by 6 gives you 1350 cm^2
