What is the formula related vertices and edges?

There is not a specific formula fro vertices and edges. The Euler characteristic links the number of vertices, edges AND faces as follows: E + 2 = V + F for a simply connected polyhedron.


What states that the number of edges equals the number of faces plus number of vertices-2?

The Euler characteristic.


How many eadges does a pyramid have?

It depends on the base of the pyramid. To find it, add the number of edges of the vertices is of the base to its number of edges. Example: for a square pyramid, there is 4 vertices and 4 edges in the base. The Edges of the pyramid is then 4+4 which equals 8.


Which 2 shapes have the same number of edges and vertices?

no numbers have the same number of edges and vertices


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


What is a shape that has equal number of faces equal number edges and equal number of vertices?

A sphere- there are no faces, edges or vertices


What is the number of faces vertices and edges of a rectangular prism and a rectangular pyramid?

for any prism , number of ___ + number of vertices = number of edges + ___


In a triangular prism what is the ratio of the number of vertices to the number of edges?

In a triangular prism, there are 6 vertices and 9 edges. The ratio of the number of vertices to the number of edges is therefore 6:9, which can be simplified to 2:3.


What 3D shape has most vertices and edges?

There is no limit to the number of vertices nor edges.


Is there a relationship between the number of vertices and the number of edges of a prism?

Yes, there is a relationship between the number of vertices and edges of a prism. A prism has two parallel bases that are congruent polygons, and if the base has ( n ) vertices, then the prism will have ( 2n ) vertices. The number of edges in a prism is ( 3n ), consisting of ( n ) edges from each base and ( n ) vertical edges connecting the corresponding vertices of the bases. Thus, the relationship can be summarized as: for a prism with a base of ( n ) vertices, there are ( 2n ) vertices and ( 3n ) edges.
