Question

If a polyhedron has 8 faces and 10 Vertices, find the number of edges. *​

Answer 1

Answer:

From Euler's formula,

1. No. of edges, E=F+V−2.

2.⇒E=8+8−2.

3.⇒E=14.

Answer 2

Given that

The polyhedron has 8 face and 10 vertices.

From Euler's Formula,

Number of edges , E = F + V - 2

SUBSTITUTION THE VALUE

• E = 8 + 10 - 2
• E = 16
