22 edges.
it has 30 edges
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.
The snub dodecahedron is an Archimedean solid consisting of 92 faces (80 triangular, 12 pentagonal), 150 edges, and 60 vertices.
The volume of a rhombic dodecahedron, with sides of length a, isV = 16/9*sqrt(3)*a^3 = approx 3.0792*a^3
A rhombic dodecahedron is a 3-D shape (polyhedron) that has 12 rhombic faces, 24 edges (sides), and 14 vertices (points). Its dual is a cuboctahedron. If you wanted to try by yourself, get a transparent model and start counting!
A regular dodecahedron has 20 vertices. But there are other forms of dodecahedra. A rhombic dodecahedron, for example, has 14 vertices.

When you say "sides", do you mean faces or edges? A dodecahedron has 12 faces and 30 edges.
A dodecahedron can have 18 to 30 edges.

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.
