1. ## Cube volume and surface area help!

I have no idea.....

When does a cube have the same numerical value for its surface area and volume?
SA=ph+2B
V=Bh

let the side of the cube be s, then the surface area is 6s^2, and the volume
is s^3. These are equal when s=6.

3. a^3=6a^2
a=6

Sorry, I did not see the answer.
