An edge of a 3-d pentagon is the intersection of two of its adjacent faces.
All prisms have a face on each end. Additionally, they will have a number of faces corresponding to the number of sides on the polygon that is on an end. For a triangular prism, that's 2 + 3 = 5 faces. For a square prism, that's 2 + 4 = 6 faces. For your pentagon prism, that's 2 + 5 = 7 faces.
