anonymous · Answer

Euler's formula is 
Vertices - Edges + Faces = 2

anonymous · Answer

If its Verticies - Edges + faces how would you get 2 @saloniiigupta95

Wait... just a sec... I have got this formula ... somehow before ... posting a link...

http://www.ics.uci.edu/~eppstein/junkyard/euler/ Check this... Here it is number of vertices, edges and faces...

anonymous · Answer

eulers formula is as follows:

Vertices - Edges + Faces = 2

In this case, we want to know how many faces there will be. So, solve for that value.

Vertices - Edges + Faces = 2
Faces = 2 - Vertices + Edges

or 

F = 2 - V + E

All you have to do now, is plug in a value for the vertices and the edges, and you have your answer waiting!
