Question

using Euler's formula find the unknown.vertices 12 and faces 4 edges?​

Answer 1

Please write the question correctly!

If you have written vertices = 12 and faces = 4, here is your answer-

The euler's formula says

F + V = E + 2

$= > 4 + 12 = e + 2$

$= > 16 = e + 2$

$= > e = 14$

hence the number of edges is 14.
