A pentagon is a polygon that has 5 sides, 5 vertices and a flat face
6 flat surfaces - known as faces, 12 edges 8 vertices.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
If they are flat, they are faces. If they are pointed, they are vertices and if they are thin and long they are edges.
