What do you call a 3D figure whose surfaces are polygons?

• polyhedron

• space figure

• solid figure

• plane figure

Can we consider a cone, cylinder and a sphere a polyhedron? Why?

• No. It is because they have curved face, not flat, surfaces.

• Yes. It is because their surfaces are polygons
