According to the Euler characteristic for polyhedra,
V + F = E + 2 where V = Vertices (not vertexes), F = Faces and E = Edges.
So F = 12

What is the number of an icosahedron or the number of vertices of a dodecahedron?
An icosahedron has 20 faces, 30 edges, and 12 vertexes. 5 polygons meet at each vertex and each face has 3 vertexes (therefore made of triangles). A dodecahedron has 12 faces, 30 edges, and 20 vertexes. 3 polygons meet at each vertex and each face has 5 vertexes (therefore made of pentagons).
