A cone has 1 face, which is its flat circular base. In addition to this face, it has 1 curved surface that forms the side of the cone. Therefore, if considering only flat faces, a cone has one face, but including curved surfaces, it has one face plus one curved surface. The cone also has 1 edge, where the base meets the curved surface, and 1 vertex (the apex) at the tip of the cone

. In summary:

• Faces (flat): 1 (the base)
• Curved surface: 1 (the curved side)
• Edges: 1
• Vertices: 1
