Add the number of faces of the shape to the number of vertices, and then subtract 2 to give you the number of edges.

This works for most polyhedrons.

I hope I have helped :)

ALSO, take the number of vertices, divide that by two, then add that answer to the number of vertices... that will give you the number of edges unless it is a pyramid.

Here is one that is GURANTEED TO WORK BECAUSE I HAVE TRIED IT. Here is is: Edge= 2 times(Vertice-1)
