anonymous · Answer

F + V - E = 2
F - faces 
V - vertices 
E - Edges
count them & put in the eq :)

anonymous · Answer

well I think there is 5 face... 5 vertices.... and 8 edges

anonymous · Answer

thats 5+5-8= 2

anonymous · Answer

so the edges and vertices are 13 ?

random231 · Answer

arent there 8 vertices?

anonymous · Answer

maybe

anonymous · Answer

i thought it was a triangular prism?

anonymous · Answer

i got 13 am i right?

anonymous · Answer

i think yes :D

random231 · Answer

by counting from the foto im getting 16

anonymous · Answer

okay but the photo is net.. we need the edges and vertices of the actual polyhedron once its built

random231 · Answer

awww sorry ok ok yea

anonymous · Answer

alright so ill put 13. thanks!

anonymous · Answer

see this if you still have confusion http://www.mathsisfun.com/geometry/polyhedron.html

superdavesuper · Answer

from @annas link, this should be an octahedron because it has 8 faces:
"
	Octahedron
4 triangles meet at each vertex
8 Faces
6 Vertices
12 Edges"

so V=18, E=12

anonymous · Answer

Maybe you're right @superdavesuper lemme take another look at this!

anonymous · Answer

You're right 12 edges and 6 vertices, that makes the answer 18. Thanks for the fix I almost missed that ! @superdavesuper
