A dodecahedron is a regular polyhedron that has 12 Faces, 20 Vertices, and 30 Edges. It is 3-D just like most other polyhedra. All its faces are pentagons; its dual polyhedron is an icosahedron.
Elementary School Guy: Did you see that crazy dodecahedron over there? It's like a million pentagons combined!
High School Guy: Umm.. Yah? I already know about polychorons and all shapes.
Elementary School Guy: O_O you know 4D Shapes?
High School Guy: Yah. -.- *Walks away*
