A cone has 1 face, 0 edges, and one vertex. The face is the circular flat area. The cone can roll, so it has no edges. Edges have to be straight. The vertex is the pointy thing opposite to the face.

A cone has 1 face, 0 edges, and one vertex. The face is the circular flat area. The cone can roll, so it has no edges. Edges have to be straight. The vertex is the pointy thing opposite to the face.
The answer depends on the number. Note that the question does not require the solids to be in the form of cubiods (rectangular prisms).
