Question

If F=6 , V=7 find E​

Answer 1

Given:

The number of faces (F) = 6 and the number of vertices (V) = 7

We have, to find the value of the number if edges(E).

Solution:

We know that:

Euler's Formula:

V - E + F = 2

⇒ E = V + F - 2

∴ E = 7 + 6 - 2

⇒ E = 11

∴ The number of edges(E) = 11

Thus, the number of edges(E) is "equal to 11"

Answer 2

Given:

F = 6 , V = 7

To find:

The value of E.

Solution:

From given, we have the data as follows.

The number of faces (F) = 6

The number of vertices (V) = 7

Now, we are supposed to find the value of the number of the edges(E).

We know that:, the Euler's Formula is given as follows.

V - E + F = 2

Substitute the values of given parameters in the above equation, that is, the values of F and V. So, we get,

7 - E + 6 = 2

Continue the further calculation.

∴ E = 7 + 6 - 2

⇒ E = 11

∴ The number of edges (E) = 11

Therefore, the number of edges (E) is "equal to 11"
