But if the length of the side of the cube is ' K ' units, then the surface area of the cube is 6K² units², and the volume of the cube is K³ units³.
The ratio of the surface area to the volume is
(6K² units²) / (K³ units³) = (6) / (K units) .
So for example, if the side of the cube is 2 inches, then the ratio of surface area to volume is "3 per inch".
That's the answer. I did the whole thing in order to earn the points, but I don't expect you to understand much of it, because I see from your username that you suck at math. I'm sorry you decided that. Now that you've put up the brick wall, it'll be even harder for any math to find its way in there, and you'll miss out on a lot of the fun.
