None. It's rectangular.
A square pyramid has one base, and it is a square. That's why it's called a square pyramid. And because the base is a square, it has four sides.
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 8 edges, 6 vertices 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.
