Question

Q4. If the number of faces and
1 point
vertices of a polyhedron are 11 and 8
respectively, then number of edges
*
are​

Answer 1

Answer:

According to Euler's formula,

F + V - E = 2

where F is the number of faces

V is the number of vertices

E is the number of edges of a polyhedron.

Given : F = 11

V = 8

Then, E = F + V

which is ,. E = 11 + 8. = 19

Therefore the number of edges of the polyhedron is 19
