Question 198748
<font face="Garamond" size="+2">


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:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A_c(s) = 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:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ V_c(s) = s^3]


The ratio of the surface area to the volume is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{A_c(s)}{V_c(s)}=\frac{6s^2}{s^3}=\frac{6}{s}]


Just divide 6 by the length of the side.
