Question

what will be the number of Edge if therw are 12 vertices and 20 faces​

Answer 1

Answer:

30 edges

Answer. According to the formula given by Euler. Therefore, there are 30 edges of a polyhedron having 20 faces and 12 vertices.

Answer 2

ANSWER-30

ACCORDING TO THE EULER

F+V=E+2

Then

given,

v=12

F=20

E=?

20+12=E+2

32=E+2

E=32-2

E=30

Therefore the number of edges are 30
