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.

A polyhedron with 12 vertices and 30 edges has how many faces?
A polyhedron has 30 edges and 12 vertices. How many faces does it have
Why is a sphere not a polyhedron?
A sphere is not a polyhedron because it has no edges, no vertices and no flat faces The word 'polyhedron' means many faces.

How many edges and vertices in a polyhedron?
The number of edges and vertices ina polyhedron will depend on the polyhedron one selects either to study, build or etc...

Where do edges meet in a polyhedron?
Edges meet at a vertex.
What do you call an endpoint where two edges intersect on a polyhedron?
An endpoint where two edges intersect on a polyhedron is called a vertex.
How many faces and edges does a 3d polyhedron have?
The only thing that can be said that there must be at least 4 faces and at least 6 edges and that the polyhedron must satisfy the Euler criterion which requires that: Faces + Vertices = Edges + 2.
