The surface area of a cube is given by the formula:
Surface Area=6a^2
The variable "a" being the length of the edges.

Whereas, the volume of a cube is given by

Therefore, we could solve for a from the given value of the surface area, 96 sq. cm.


Taking the square root of both sides, we get:
 \sqrt{16cm^2} =\sqrt{a^2}

So, a=4 cm. 

Now, we will use this value of a to get the volume.

Taking the cube, we get:
Volume=64 cm^3

The volume of a cube is (s^2)6; this is the formula. So, the area of it is 96 cm^2, right? So multiply it by 6, and the volume of it is 576 cm^3. There's no answer on your choices.

I'm pretty sure I answered the question sufficiently. The volume of a cube is a^3. You can check it on other sources. And the given is surface area, not area.
