A. 64 cm
3
B. 64 cm

D. 96 cm

1 answer

The surface area of a cube can be found by multiplying the side length by itself, and then multiplying that by 6 (since a cube has 6 equal sides):

Surface area = (side length)^2 * 6

In this case, the side length is 4 cm:

Surface area = (4 cm)^2 * 6

Surface area = 16 cm^2 * 6

Surface area = 96 cm^2

So the correct answer is:

C. 96 cm^2
