alleryA square pyramid has how many faces, edges and vertices in that order?
A5, 10, 6
B6, 12, 8
C5, 8, 5
D4, 6, 4
Answer & Solution
Correct answer: C. 5, 8, 5
1. Faces: 1 square base + 4 triangles = 5.
2. Edges: 4 on the base + 4 up to the apex = 8.
3. Vertices: 4 on the base + 1 apex = 5.
4. Check with Euler: 5 + 5 - 8 = 2.
