Best Answer: a cone has Facse: 2 (the base and the slanted surface) Edges: 1 (the joining of base with the slanted surface) Corners: 1 (the apex) You just need to visualize the cone. Source(s): TJ Â· 9 years ago.
The base is a rectangle, so it has four edges. Each edge is the base of a face. That makes 4 + 1 = 5 faces. The edges are the four sides of the rectangle and the four edges connecting each vertex of the rectangle to the apex. That's 4 + 4 = 8 edges. The vertices are the four vertices of the rectangle and the apex.
