A cone has exactly one flat surface, which is its circular base. The rest of the cone consists of one curved surface that tapers from the base to the apex (vertex)
. To summarize:
- Flat surfaces (faces): 1 (the circular base)
- Curved surfaces: 1 (the lateral curved surface)
- Edges: 1 (the circular edge where the base meets the curved surface)
- Vertices: 1 (the apex or tip of the cone)
Thus, the cone has one flat surface in total
