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 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.
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.
How many sides edges and faces does a septagonal prism have?
Sides = Faces: 9 Edges: 21.
How many edges are there for octagon?
An octagon has 8 sides or edges
What are edges of a shape?
the edges of a shape are basicly the sides of a shape
How is the total number of sides of the faces related to the number of edges?
Faces + Vertices = Edges + 2
What is the number of edges in a cuboid?
6 sides.
What is the expression for the number of edges of a prism?
Edges = 3 x number of sides in end of prism For example, a hexagonal prism would have 3 x 6 = 18 edges since there are 6 sides to a hexagon.
How many number edges does a cube have?
6 sides
How do you find the n number of a shape?
count the sides or edges.
What is the sum of the number of corners edges and sides on a cube?
30
What do you notice about the number of edges of a prism?
It's three times the number of sides of the base.

How many sides and edges does a cylinder have?
Two sides and no edges!
What is the relationship between the number of faces and edges of a triangular pyramid?
Every face has 3 edges. CAUTION: DO NOT multiply the # of sides by 3, as that will not get you the # of edges. a triangular pyramid has 7 edges
How may edges does a decagonal prism have?
3 times the number of sides on each base. 3*10 = 30 edges.
Edges on a pyramid?
That would be 2 times the number of sides in the base. For example, a triangular pyramid has 6 edges. A rectangular pyramid has 8 edges. An octagonal pyramid has 16 edges.
