I don't know what a 'centiment' is. I know what a centimeter is, perhaps that is what you meant.

The surface area of a cube is given by:



because there are six faces each having an area equal to the length of the side squared.

The volume of a rectangular solid is the length times the width times the height, but for a cube the length, width, and height are all equal so the volume of a cube is:



The ratio of the surface area to the volume is:



Just divide 6 by the length of the side.
