## Main Question or Discussion Point

The volume of a triangular prism is given by:

v = ½ |

Where b and c are two of the sides of the triangular face of the prism, and a is the length of the prism.

The volume of a rectangular/parallelogram-based pyramid is given by:

V = ⅓ |

My question is, what are a, b, and c?

Is it necessary, in general, that b and c be the lengths of two of the sides of the base?
