Question

A number cube has edges of 8 centimeters. What is the surface area of the number cube?

-64 square centimeters
-192 square centimeters
-384 square centimeters
-512 square centimeters

Answer 1

384 square centimeters

Explanation:

The surface area formula for a cube is 6L^2

(L=length or in this case edge)

Plug in values and solve the formula.

SA=6L^2

SA=6(8^2)

SA=6(64)

SA=384 square centimeters
