Question

a ployhedron has 7 vertical and 10 faces .how many edages it have. please sole by step by step ​

Answer 1

Step-by-step explanation:

Use Euler’s formula:

F+V -E = 2

So 7 +10 - E = 2

E = 17 - 2

= 15

So it has 15 edges.

Answer 2

Answer:

15

Step-by-step explanation:

Vertices (V) = 7

Faces (F) = 10

According to Euler's Formula,

F + V - E = 2

=> 7 + 10 - E = 2

=> 17 - E = 2

=> 17 - 2 = E

=> E = 15
