A decahedron is a closed 3-D shape with ten polygonal faces. There are 32,300 topologically different decahdra and, since none of these are regular, the term is ambiguous. The formula for the volume of a decahedron will depend on which one of the 32,300 decahedra it is, and in many cases it is likely to be quite a complicated formula.
