A regular dodecahedron has 20 vertices, 12 faces and 30 edges.
A dodecahedron can also be a endacagon based pyramid which has 12 vertices, 12 faces and 22 edges, or
A decagon based prism which has 20 vertices, 12 faces and 30 edges, or one of many other configurations.

12 Faces, 30 Edges, 12 vertices
By definition, a dodecahedron must have twelve faces. So it must be an decagonal prism. Edges = 30 Faces = 12 Vertices = 20
A dodehedron does not exist. A regular dodecahedron has 20 vertices, 30 edges and 12 faces. A dodecahedron must have 12 faces, but it can have any number from 8 to 20 vertices and so 18 to 30 edges.
Dodecahedrons are a shape with 12 faces, 30 edges and 20 vertices.
The snub dodecahedron is an Archimedean solid consisting of 92 faces (80 triangular, 12 pentagonal), 150 edges, and 60 vertices.
