Proposition: Prop. 12.08: Volumes of Similar Tetrahedra are in Cubed Ratio of Corresponding Sides
Euclid's Formulation
Similar pyramids which also have triangular bases are in the cubed ratio of their corresponding sides.
* Let there be similar, and similarly laid out, pyramids whose bases are triangles $ABC$ and $DEF$, and apexes the points $G$ and $H$ (respectively).
* I say that pyramid $ABCG$ has to pyramid $DEFH$ the cubed ratio of that $BC$ (has) to $EF$.
