The mathematician Euler created a formula that relates the vertices, edges, and faces/sides. The formula states that:
V - E + F = 2
When V is the number of vertices, E is the number of edges, and F is the number of faces.
How do the number of edges relate to the number of sides
Using simple algebra this formula can be modified so the number of edges is related to the number of faces:
V - E + F = 2
V + F = 2 + E
V + F - 2 = E
E = V - 2 + F
The edges are equal to the vertices plus the faces subtract two.
How do the number of sides relate to the number of edges
Using simple algebra this formula can be modified so the number of faces is related to the number of edges:
V - E + F = 2
V + F = 2 + E
F = 2 + E - V
The faces are equal to the edges subtract the vertices plus two.

How can the number of edges of the base of a prism be used to calculate the number of edges?
The number of edges of the base of a prism can be used to calculate the total number of edges by first determining the number of edges on one base. For example, a rectangular prism has 4 edges on its base. Then, multiply this number by 2 to account for the top and bottom bases. Finally, add the number of edges around the sides of the prism, which is the same as the number of edges on the base. So, in total, the number of edges of a prism can be calculated as 2 times the number of edges on the base plus the number of edges around the sides.
Can a prism have seven more edges than it has vertices?
Oh, isn't that a happy little question! Let's think about it together. A prism has 2 bases and the same number of edges as the number of sides on those bases, plus the number of edges connecting the corresponding vertices on the bases. So, a prism can't have seven more edges than vertices because the number of edges is determined by the number of sides on the bases and the number of vertices.
How many edges on a pyramid?
A pyramid is a generic term, used to describe a three dimensional shape with a polygonal base and triangular sides that meet at an apex above the base. The base can be a polygon with any number of sides and the number of faces, edges and vertices of a pyramid depend on this number of sides. If the base is an n-sided polygon, then the pyramid has 2n edges.
How many edges does a polygon have?
A polygon has NO edges. However, it has 'any number' of sides. The word 'poly' is from Latin, and means 'many'. The word 'gon' is a plain 2-dimension figure.
Which statement is true about the number of edges of any prism?
It is three times the number of sides on a base of the prism.
