The number of edges and vertices ina polyhedron will depend on the polyhedron one selects either to study, build or etc...
Probably a pentagonal prism.
Edges join two vertices. Three or more edges meet at a vertex (it could be two if not in a polyhedron).
It has 6 vertices.
There is not a polyhedron with the given number of faces, edges and vertices.
A 20-sided polyhedron is called an icosahedron. It has 20 equilateral triangle faces, 30 edges, and 12 vertices. It is a regular convex polyhedron with rotational symmetry.
The number of edges and vertices ina polyhedron will depend on the polyhedron one selects either to study, build or etc...
A polyhedron has 30 edges and 12 vertices. How many faces does it have
A polyhedron must have at least 4 faces, at least 4 vertices and at least 6 edges.
Probably a pentagonal prism.
This polyhedron has 7 vertices and 12 edges.
Edges join two vertices. Three or more edges meet at a vertex (it could be two if not in a polyhedron).
For a simply connected polyhedron,Faces + Vertices = Edges + 2
It has 6 vertices.
There is not a polyhedron with the given number of faces, edges and vertices.

A sphere is not a polyhedron because it has no edges, no vertices and no flat faces The word 'polyhedron' means many faces.
