If a cube number does not measure a(nother) cube number then the side (of the former) will not measure the side (of the latter) either. And if the side (of a cube number) does not measure the side (of another cube number) then the (former) cube (number) will not measure the (latter) cube (number) either. * For let the cube number $A$ not measure the cube number $B$. * And let $C$ be the side of $A$, and $D$ (the side) of $B$. * I say that $C$ will not measure $D$. * And so let $C$ not measure $D$. * I say that $A$ will not measure $B$ either.
