A pyramid has a square base. How many edges does the pyramid have?
(A) 8
(B) 6
(C) 12
(D) 5
(E) 3
Since the pyramid has a square base, the base of the pyramid has 4 edges (one for each side of the square).

An edge joins each of the 4 vertices of the square to the apex of the pyramid, as shown.

In total, a pyramid with a square base has 8 edges.
