A square has 1 face
One side of a square would be untouched with only 3 triangle faces attached to it. To make an entire closed shape, it would need another part or some 3 dimensional bending would need to take place. A pyramid has 1 square face and 4 triangle faces. A pyramid could also have 4 triangle faces where one triangle substitutes the square face.
A square pyramid has 5 faces. It has 1 square face and 4 triangle faces.
