6 faces 8 vertices 12 edges because... # of faces + # of vertices = # of edges - 2
5 faces, 5 vertices and 8 edges for a square pyramid.

4 faces, 4 vertices and 6 edges for a triangular pyramid.

The edge length of a rectangular box is either the length or the width. The longer side of the rectangle is the length and the shorter side is considered the width.

Answer 3

4 times (length plus width plus height).
