well actually it is a prism. If you mean a 5 sided pyramid with the 6 side being the bottom it would be called a Pentagonal Pyramid
A cone by definition has only two sides. A five-sided pyramid can refer to either a square-based pyramid (four angled sides and the base) or a pentagonal-based pyramid (five visible sides).
A five sided polygon is called a pentagon because pentagon means five sided polygon I think.
If you mean a pyramid with a four sided base, it is a square pyramid. If you mean one with four faces, it is a tetrahedron.
A tetrahedron, but you can also think of it as a pyramid. -edit: actually it would be a pentahedron, which may look like a four sided pyramid in which you can see the bottom, or it may look like a triangular prism. Tetra- four, Penta- five.

A 7 sided pyramid would be called a heptahedral or heptahedron.
A five sided pyramid! Ha!
A four sided pyramid is called a square based pyramid. It has a square base and four sides,(called edges,) that join at the apex. (the top of the pyramid.)
A triangular pyramid.
A cone by definition has only two sides. A five-sided pyramid can refer to either a square-based pyramid (four angled sides and the base) or a pentagonal-based pyramid (five visible sides).
A five sided polygon is called a pentagon because pentagon means five sided polygon I think.
A triangular pyramid A triangular pyramid has four sides - each of which is a triangle. There cannot be a three sided pyramid. If you mean a 3 sided Pyramid with its base being the forth side it would be a Quadrangle. A four-sided triangular solid is also called a tetrahedron, and two interlaced are called a Star Tetrahedron.
If you mean a pyramid with a four sided base, it is a square pyramid. If you mean one with four faces, it is a tetrahedron.
