A cone has either one or two surfaces and either one or no edges.
A cone has one curved edge
A cone has a curved base edge and 1 vertex
Two: inside and outside.
One curved surface (two if it is hollow) and no edges.
ther is 20 surfaces on a cone because the is 1 on it sharp part * * * * * In fact, one flat surface (and one curved one).
A cone has one curved surface.
It has one.
It has a flat base, a curved surface area, a circular edge and one vertex.
A cone has one curved edge
A cone has a curved base edge and 1 vertex
A cone has one face - its base - and one edge but no vertices. Vertices only occur at the meeting of two straight surfaces.
Two: inside and outside.
it has 67 bases
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.
