Template:Volume of Parallelepiped/doc

This template is used by other templates to calculate the atomic packing factor.

Wikipedia:
 * If a, b, and c are the parallelepiped edge lengths, and α, β, and γ are the internal angles between the edges, the volume is
 * $$ V = a b c \sqrt{ 1 + 2 \cos(\alpha) \cos(\beta) \cos(\gamma) - \cos^2(\alpha) - \cos^2(\beta) - \cos^2(\gamma) \, }. $$
