By definition, an icosahedron has 20 faces. The number of edges can be 30 (Platonic solid), 38 (19-gonal pyramid), 54 (18-gonal prism). Other, topologically different icosahedra also exist but are difficult to describe in just words.

A polyhedron that has twice as many edges as faces is known as a triangular prism. In a triangular prism, there are 5 faces (2 triangular and 3 rectangular), 9 edges, and 6 vertices. The relationship between the edges and faces in this case satisfies the condition of having twice as many edges as faces.
