Question

need help. Can anyone help?

Answer 1

Ask away :)

Answer 2

Do you know Euler's Formula?

Answer 3

Not familiar with it, sorry.

Answer 4

I do

Answer 5

You do!
E-F+V=2?

Answer 6

Oh that one. Oh well this one too lol :)

Answer 7

it's not F+V-E = 2?

Answer 8

Ok here is my question. First, how do I thank you for your help? Second, what is the sum of the number of vertice, edges, ad faces of a dodecahedron?

Answer 9

Ok well the prefix "dodeca" is telling 12, so it's a polyhedron with 12 faces (F)

Answer 10

Right. But what about the other 2 parts?

Answer 11

Well you can try counting how many vertices there would be, in this case there are 20

Answer 12

I'm sure there is a systematic way :(
Thanks for your help though

Answer 13

From there you can use the formula to find out how many edges you have
F+V-E = 2
12+20-E=2
32-E=2
30 = E
