Faces, edges, and vertices

What does the generator do?

The generator shows one of these solids: cube, cuboid, pyramid, or triangular prism. It asks how many faces, edges, or vertices the solid has.

How to use it

Faces are the flat surfaces of the solid. Edges are the lines where two faces meet. Vertices are the pointy corners where at least three edges meet. Count them on the picture and type the number.
