In geometry, a decahedron is a polyhedron with ten faces. There are 32300 topologically distinct decahedra[1][2] and none is regular, so this name is ambiguous.
With regular faces:
- Octagonal prism (uniform 8-prism)
- Square antiprism (uniform 4-antiprism)
- Square cupola (Johnson solid 4)
- Pentagonal dipyramid (Johnson solid 13, 5-bipyramid)
- Augmented pentagonal prism (Johnson solid 52)
With irregular faces it can also be:
- Pentagonal trapezohedron (5-trapezohedron, antiprism dual) — often used as a die in role playing games, known as d10
- Enneagonal pyramid (9-pyramid)
