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)

How does the relationship compare among the number of vertices faces and edges for a pyramid?
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
What is the relationship between faces vertices and edges on a 3D shape?
Their relationship is modelled by the equation F + V = E + 2, where F is the number of faces, V is the number of vertices, and E is the number of edges.
How many faces edges and vertices does a rombus have?
2 faces, 4 edges, and 4 vertices 2 faces, 4 edges, and 4 vertices
How many faces edges and vertices does a rectangular prism have?
Faces: 6Vertices [or corners]: 8Edges: 12eight.
What is the relationship between faces edges vertices of polyhedra?
The Euler characteristic for simply connected polyhedra isF + V = E + 2 where F = # faces, V = # vertices and E = # edges.
What is the relationship among the vertices's faces and edges of polyhedrons?
If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
How does the relationship compare among the number of vertices faces and edges for a pyramid?
