Question

A solid has 20faces and 12 verticels.find the no. of edges​

Answer 1

Step-by-step explanation:

Therefore, there are 30 edges of a polyhedron having 20 faces and 12 vertices.

Answer 2

$eulers \: formula = f + v - e = 2$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 20 + 12 - e = 2$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 32 - e = 2$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = e = 32 - 2$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = e = 30$
