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.

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.

2 flat and 1 curved

It has a flat base, a curved surface area, a circular edge and one vertex.

It has one.

Flat surfaces: 6Curved surfaces: 0.

Two: inside and outside.

A prism has no curved surfaces. It has 5 or more flat faces.

None. A cuboid has six flat surfaces.

A triangular prism contains zero curved and 5 flat surfaces.

a cone has one flat surface one vertex and no edge.

it has 0 curved faces

a cube has 0 curved faces and 6 straight face

Just one at the base, the rest is a curved surface

It only has one. the face going around the cone is called the lateral surface

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.

The geometrical object known as a cone has no planar faces, two curved surfaces, no edges and one vertex. A "real" object often called a cone is a portion of a half cone. That has one base, a curved surface, and one vertex.

1 because all of the shape is curved except for the flat surface on the bottom

Flat surfaces?... Well, a cone has a circle on the bottom (as its base) and, when rolled out, a rectangle for its side that the apex is part of at the top. So I'd say the answer to your question is "2," if I have a correct understanding your question. ~OneAndOnly13
