Question

if the number of faces of a solid shape are 7 and number of vertices is also 7, what would be the number of edges ?​

Answer 1

using the euler's formula :

F+V-E=2

7(Faces)+7(Vertices)- edges =2

14- edges = 2

14-2= edges

12= edges

Answer 2

The number of edges are 12.

Step-by-step explanation:

Consider the provided information.

Euler's Formula tells us that if we add together the number of faces and vertices and subtract the number of edges, we will receive 2 as our response. The formula is composed as F + V - E = 2.

Substitute F = 7 and V = 7 in above formula.

7 + 7 - E = 2

14 - E= 2

E = 12

Hence, the number of edges are 12.
