The surface area of a cube is 384 square inches. What is the volume of the cube????
A. 8 cubic inces
B. 16 cubic inches
C. 256 cubic inches
D. 512 cubic inches

Let the side length be a.
The area is 6 a^2 = 384, so
a^2 = 64
That should tell you what the value of a is.
The volume of the cube is a^3. It is one of your choices. Do the numbers.
