A polyhedron can have any number of faces 4 or higher.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
A polyhedron with the fewest number of faces is a triangular pyramid - it has four faces including the base.
A square pyramid has 5 vertices and 8 edges. A square pyramid has a square for a base and four triangular faces that connect at the top. The top is one vertex. The four corners of the square base are the other four vertices. The square base has four edges. The other four edges extend from the vertex at the top to the vertices of the square base. This pyramid also has 5 faces.
It's an Octohedron, which has 8 triangular faces. Think of one of the great pyramids in Egypt, with a square base and four triangular sides. Take two of these, turn one upside down, and glue them together along the square base. You wind up with 8 triangular faces, and 12 edges!
A pyramid has a polygonal base with all other sides being triangles. As the Egyptians famously demonstrated, a common pyramid has a square base with four triangles meeting at a vertex, but any polygon - regular or irregular - can be used as the base of such a polyhedron.
A square based pyramid.
A square based pyramid.
A polyhedron that has two congruent faces is called a prism. It means that when it is cut at the cross-section, the shape is the same as its base.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
A polyhedron with the fewest number of faces is a triangular pyramid - it has four faces including the base.
An octahedron formed by joining together (base-to-base) two square-based pyramids.
There would be 8 faces. Each square pyramid has 1 square face (its base) and 4 triangular faces. When you glue the squares together, you get a new polyhedron with 8 faces.
A regular polyhedron has equal size faces as in the case of a tetrahedron which is a triangular base pyramid that has 4 equilateral triangle faces.
A Pyramid; Four sides and the base.
Other? The bottom is the base. And the sides are called faces.
A square pyramid has 5 vertices and 8 edges. A square pyramid has a square for a base and four triangular faces that connect at the top. The top is one vertex. The four corners of the square base are the other four vertices. The square base has four edges. The other four edges extend from the vertex at the top to the vertices of the square base. This pyramid also has 5 faces.
A polyhedron has only polygonal faces and any one of them can be considered a base. Therefore a polyhedron with 0 bases cannot exist.
