A cube is a specialized form of a rectangular prism.
Another word for a 2 dimensional pattern is a net. A net of a rectangular prism would include all the faces of one: so 2 bases and 4 faces.
A rectangular pyramid has 5 bases. The base of a pyramid is the polygon upon which the pyramid stands, and in the case of a rectangular pyramid, there are four triangular faces that meet at a single rectangular base. So, the total number of bases in a rectangular pyramid is 1 (rectangular base) + 4 (triangular faces) = 5 bases.
