it has 0 curved faces
a cube has 0 curved faces and 6 straight face
An empty cone (like an ice-cream cone) doesn't have any flat surfaces. It has two curved surfaces, one outside and one inside. A solid cone has a flat base, and one other curved surface.
When a curved surface is represented on a flat surface, usually either distances or directions must be distorted. Various "projections" exist to minimize these distortions in whatever way is important to the cartographer.
