A pentadecahedron is a closed 3-d shape with 15 polygonal faces. There are almost 24 billion topologically different convex versions and, since none of these are regular, the term is ambiguous. The number of edges will depend on which specific 15-hedron you have in mind.

pentadecahedron * * * * * No. Even though I do not know the correct answer, I do know that that is not the correct answer. A pentadecahedron has 15 faces - NOT 15 edges. Polyhedra often have names with Greek prefices which refer to the number of faces.
