A pentagonal prism will have 15 edges.
A pentagon is a 2 dimensional object. The 3 dimensional object, with 12 pentagonal faces, is called a dodecahedron.
If you are thinking of a solid with pentagonal faces, a dodecahedron, there are twelve pentagons
It is a dodecahedron, and you can see images at the link below. Drawing it, though, depends on your artistic skill at projecting 3-d images onto 2-d.
The vertex of a 3D pentagon is 10. :)

Oh, dude, a 3D pentagon has five sides and five vertices. It's like a regular pentagon, but in 3D, so it's got some depth to it. Just imagine a 2D pentagon trying to be all fancy and three-dimensional.
