## Answers ( )

Answer:We are given with the number of faces and vertices and we have to find the number of edges by using Euler’s formula.

GiveN:We have to find no. of edges by using Euler’s formula.

EULER‘SFORMULA:Here F is the number of faces, V is the number of vertices and E is the number of edges.

So, plug in the number of faces and vertices given to get the number of edges:

➝ F + V – E = 2

➝ 18 + 10 – E = 2

➝ 28 – E = 2

➝ E = 28 – 2

➝ E = 26

So, the Number of edges in the solid is:

And we are done !!
