None!
None. It's rectangular.
A triangular pyramid, also known as a tetrahedron, has one circular base. However, it actually has four triangular faces, with three of them meeting at each vertex. The base is not circular; it is triangular, while the other three faces are also triangular. Therefore, a triangular pyramid has no circular bases.
The base is the bottom, so a square-based pyramid has ONE base.
A cube does not have any circular bases; it has six square faces. Each face is flat and has straight edges, with no curves or circular shapes. Therefore, the answer is zero circular bases.
5. one for the square bottom, and one for each side coming out from the square
A rectangular pyramid has no circular bases.
a rectangle pyramid has no circular because its just a rectangle and a triangle but together
a square pyramid has 5 a circular pyramid has none

A triangular pyramid, also known as a tetrahedron, has one circular base. However, it actually has four triangular faces, with three of them meeting at each vertex. The base is not circular; it is triangular, while the other three faces are also triangular. Therefore, a triangular pyramid has no circular bases.
A square pyramid has 1 square base and 4 triangle-shaped sides.
The base is the bottom, so a square-based pyramid has ONE base.
A square based pyramid has 5 vertices, 8 edges and 5 faces
A square pyramid has five faces, one of which is a square and the remaining four are triangles. Conventionally such a pyramid is called a square BASED pyramid and in that context it has only one base. [That definition is used to distinguish it from a pentagonal pyramid, a hexagonal pyramid, etc.] However, any one of the five faces can be at the bottom.
5. one for the square bottom, and one for each side coming out from the square
A pyramid is not normally circular but if you mean a cone then it has 1 vertex, 1 circular edge and 2 faces.
A square based pyramid has 8 edges, 6 vertices and 5 faces.
