A cone has either one or two surfaces and either one or no edges.
Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces. Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces. There are, of course, many others.
There is no edge in a SPHERE
A sphere has 0 edge.
Flat surfaces: 6Curved surfaces: 0.
There is 1 curved surface on a sphere
One.One.One.One.

There is no edge in a SPHERE
A sphere has 0 edge.
A sphere has no edges, because an edge is defined as where two faces meet. Likewise, it has no faces, because a face is defined as the flat surface of an object. Likewise, it has no corners either.
It has a flat base, a curved surface area, a circular edge and one vertex.
2 flat and 1 curved
One if it is solid, two if it is hollow
5
2 flat surfaces unless it is rolled up in which case it has 2 curved surfaces.
