Question

A solid has 9 faces and 9 vertices. Find the number of its edges

Answer 1

Answer:

Faces =9

Vertices=9

F+V-E=2

9+9-E=2

E=2-18=16

I think the question is a little wrong but u can find edges by the F+V-E=2 formula.

Answer 2

The number of edges of the solid can be identified by V-E+F= 2.

Explanation:

• The number of vertices is 9.
• The number of faces is 9.
• The number of edges= 9-E+9=2
• Where 9+9-2= E
• E= 16 edges.
• Hence the total number of edges of the solid is equal to 16.
• This formula is applicable for all types of solids whose number of vertices and faces are given. The total number of faces in the solid are dependent on the terms of edges and vertices. Vertices connect two edges and faces of a solid.
