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:
 = 6s^2)
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:
 = s^3)
The ratio of the surface area to the volume is:
}{V_c(s)}=\frac{6s^2}{s^3}=\frac{6}{s})
Just divide 6 by the length of the side.
