Question

A polyhedron with 20 vertices and 30 faces has how many
edges?​

Answer 1

Answer:

A polyhedron with 20 vertices and 30 faces has 12 edges

Answer 2

Answer:

we can solve it by Euler's formula.

Euler's formula= V - E + F =2

here Vertices, V= 20

Faces,F =30

putting values ⤵️

=) 20-E + 30 =2

50- E= 2

50-2 = E

48 = E

hence, Edges, E = 48
