What is the surface area of the cube below? A. 508 units2
B. 512 units2
C. 320 units2
D. 384 units2

D. 384 units^2

Step-by-step explanation:

The surface area of a cube can be found using the following formula:

S=6s^2

where s is the side length.

In this case, the side length of the cube is 8 units.

s=8 units

Substitute 8 units in for s.

S=6*(8 units)^2

First, evaluate the exponent.

(8 units)^2=8 units * 8 units= 64 units^2

S=6* 64 units^2

Multiply 6 and 64

S=384 units^2

The surface area of the cube is 384 square units, therefore D. 384 units^2 is correct.
