1.

The number of edges of a polyhedron, which has 7 faces and 10 vertices, is1. 152. 173. 134. 14

Answer» Correct Answer - Option 1 : 15

Given:

Number of faces, (F) = 7

Number of vertices, (V) = 10

Formula used:

From Euler's formula,

No. of edges, (E) = F + V − 2

Calculation:

No. of edges, (E) = F + V − 2

⇒ E = 7 + 10 − 2

⇒ E = 17 − 2

⇒ E = 15

∴ The number of edges of a polyhedron is 15
