Question

A square base pyramid has 5 faces and 8 edges. Find the number of vertices?
1. 8
2. 7
3. 6
4. 5

Answer 1

Correct Answer - Option 4 : 5

Given:

Number of faces = 5 

Number of edges = 8

Formula Used:

Faces + Vertices = Edges + 2

Calculation:

Faces + Vertices = Edges + 2

⇒ 5 + Vertices = 8 + 2

⇒ Vertices = 5

∴ A square based pyramid has 5 vertices.

The correct option is 4 i.e. 5
