When you say "sides", do you mean faces or edges? A dodecahedron has 12 faces and 30 edges.
A dodecahedron is a polyhedron with 12 faces, each of which is a regular pentagon. In a dodecahedron, the faces are not parallel to each other. The planes of the faces intersect at various angles, giving the dodecahedron its unique shape and properties.
