### How many faces does a heptahedron have?

seven sides

A heptahedron is a polyhedron having seven sides, or faces. A heptahedron can take a large number of different basic forms, or topologies.

#### How many vertices does a tetradecahedron have?

A tetradecahedron is one of the 13 polyhedra of Archimedes. It was discussed in the 17th century by Kepler. It is sometimes called the cuboctohedron (Thomson, 1887). It has exactly 13 vertices: a central one, plus the outer ones that define 12 directions in space.

**How many faces does a Hendecahedron have?**

11 faces

A hendecahedron (or undecahedron) is a polyhedron with 11 faces. There are numerous topologically distinct forms of a hendecahedron, for example the decagonal pyramid, and enneagonal prism. Three forms are Johnson solids: augmented hexagonal prism, biaugmented triangular prism, and elongated pentagonal pyramid.
