What is the number of edges on a square pyramid?

• A. 4 edges
• B. 8 edges
• C. 6 edges
• D. 5 edges

Answer: (B)

To determine the number of edges in a square pyramid, it's important to visualize the structure. A square pyramid consists of a square base and four triangular faces that meet at a single apex (top point). The square base contributes four edges, corresponding to its four sides. In addition to these, each vertex (corner) of the base connects to the apex by an edge, contributing four more edges. Therefore, the total number of edges is the sum of the edges from the base and the edges connecting the base to the apex, which is 4 (base edges) + 4 (connecting edges) = 8 edges. This understanding confirms that the number of edges in a square pyramid is actually 8, not 6, 4, or 5, as those counts do not account for either the triangular faces or the full connection including the apex. Therefore, the correct declaration of edges in a square pyramid reflects its full three-dimensional structure, and the count reaches 8 edges.
