12 faces 20 vertices 30 edges
Vertices: 20 Edges: 30 Faces: 12
By definition, a dodecahedron must have twelve faces. So it must be an decagonal prism. Edges = 30 Faces = 12 Vertices = 20
12 faces * * * * * Correct as far as it goes, but incomplete. 20 vertices 30 edges
19 * * * * * Actually it is 30 edges. Ten around each of the decagonal faces, and ten more connecting the corresponding vertices of the two decagons.
