That depends on the kind of polyhedron.
There are five kinds of regular polyhedra (all edges of equal length).
- Tetrahedron (four-sided pyramid) has 6 edges
- Hexahedron (cube) has 12 edges
- Octahedron (eight-sided solid) has 12 edges
- Dodecahedron (12-sided solid) has 30 edges
- Icosahedron (20-sided solid) has 30 edges
It is also possible to have a polyhedron that is not regular, with almost any number of sides and edges.
