Yes.
No, it has four.
Total Eight edges; four vertical and four at bottom.
One, two, three, four, five, six, seven, eight. The four edges on the base and the four vertices.
Eight edges (four edges on the square bottom, and one edge going from the vertex to each of the four corners of the square).
Yes.
A square pyramid does not have any curved edges; it has a total of eight edges. This includes four edges at the base, which form a square, and four triangular edges that connect the apex of the pyramid to each vertex of the base.
Five: four sloping triangular sides and a square base. It has eight edges.
A square pyramid has no curved edges; it consists of eight edges in total, which are all straight. There are four edges forming the base (the square) and four edges connecting the apex to each vertex of the base. Thus, the square pyramid is characterized by its straight edges and flat faces.
5 EDIT: It has eight edges. Four on the base, and one from each of the four corners of the base, converging to the point at the top. Snakester1962 (Supervisor)

A square has four edges, one face (assuming the "back" does not count), and four vertices. A cube has 12 edges, six faces (assuming the "inside" does not count), and eight vertices.
