Faces + Vertices = Edges + 2
This is called Euler's formula.
For example a cube has 8 vertices, 6 faces and 12 edges so:
6 + 8 = 12 + 2
14 = 14
The formula works.

What is Euler's rule?
euler's rule there are many answers but no one which one is the rigth one. his rule is: 1. V+F-E=2 2. V+F=E+2 3. too mathmatical Key Code: V= number of vertices F= number of faces E= number of edges this rule can only work on Polyhedron

What Is The Rule Connecting the faces edges and vertices of a 3D shape?
# of faces + # of edges + # of vertecies + 2
How many faces and edges and vertices's does a rectangular pyramid have?
A rectangular-based pyramid has 5 faces, 8 edges, and 5 vertices. To check if the numbers are right, the Euler's rule can be used. The formula is Faces + Vertices = Edges + 2. Clearly, the sum of the faces and vertices, which is 10, is equal to the sum of the edges plus 2, which is also 10.

Euler's rule for a polyhedron?
For a simply connected polyhedron,Faces + Vertices = Edges + 2
Euler's rule for a polygon?
The rule applies to POLYHEDRA (3D shapes) not Polygons, which are 2D Faces + Vertices - Edges = 2
Why cant you build a polyhedron with different number of faces that also has th 4 vertices and 6 edges?
Because the Euler characteristic establishes the rule that for all simply connected polyhedra, Faces + Vertices = Edges + 2 Vertices = 4 and Edges = 6 implies that Faces + 4 = 6 + 2 = 8 so that Faces = 4. So there is only one such polyhedron.
How do you find the verticies in a rectular prism?
You can count them or you can remember this rule: A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A rectangular prism has 8 vertices.
How many vertices and edges does a square pyramid have?
A Pyramid by definition has a square foundation, four sides each in the form of a triangle rising to terminate in a point. So, explain square pyramid. In mathematics a pyramid number, or square pyramidal number is a figurate number that represents the number of stacked spheres in a pyramid with a square base. Therefore on the top of the pyramid will be one sphere, underneath that will be four spheres, underneath that will be 9 spheres and underneath that will be 16 spheres. The numerical progression will be 1 - 4 - 9 - 16. So take any slice though a pyramid (side to side that is) and you will have a top, a bottom and four sides

How many faces in a pyramid?
If a pyramid has a square base then it will have 5 faces. Always look at the number of edges at the base so is the base is square which has four edges then it will have four faces plus a base. This means 5 faces. This rule works in almost all 3D objects.
