No, because a polyhedron is a solid with many flat faces. A heptagon is not a 3-D figure. However, a pyramid or prism would be a polyhedron.
A polyhedron is in a subclass of geometric solids. The difference is that a polyhedron must have flat faces and straight edges.
A Platonic solid?
A polyhedron is a three-dimensional object, not two-dimensional.
A pyramid, as well as any other solid figure bounded by plane polygons or faces, is a polyhedron.
A polyhedron is any multi-faced solid. In order to know how many pairs, you need to know how many total faces.
Polyhedron is a geometric solid in three dimensions with flat faces and straight edges.

A polyhedron is a solid shape with many sides. The word "polyhedron" does not specify a number of sides.
A polyhedron is a solid shape with four or more polygonal faces. A hexahedron is a solid shape with six polygonal faces and so is a particular type of polyhedron.
A cube is a solid figure called a polyhedron. A polyhedron is a solid figure with all flat faces. So a cone would be a solid figure but not a polyhedron becasue it has a curve and does not have all flat faces.
A triangle is not a polyhedron. A triangle is a two-dimensional figure, and a polyhedron is a three-dimensional solid. An example of a triangular-shaped polyhedron is a pyramid.
A polyhedron.
A face.
A polyhedron is any 3D solid (such as a cube) - therefore, it can have any number of faces.
