Question

If F =18 and V=10 ,then find the Value of E in Euler's formula.​

Answer 1

Given:-

• Value of F is 18.
• Value of V is 10.

⠀

To find:-

• Value of E.

⠀

Solution:-

Here,

• F = 18
• V = 10

⠀

According to the question

We know that,

⇛ Euler's Formula = F + V = E - 2

⠀

Let's do it,

→ F + V = E - 2

→ 18 + 10 = E - 2

→ 28 = E - 2

→ E = 28 - 2

→ E = 26

⠀

Hence,

• the value of E is 26.

Answer 2

Given :-

• Value of F = 18
• Value of V = 10

To Find :-

• Value of E by applying the Euler's formula

Solution :-

$\underline{\bf{\dag} \:\mathfrak{As\;we\;know\: that\: :}}$

→ Euler's formula = F + V - E = 2

Where ,

• F = number of faces

• V = number of vertices

• E  = number of edges

→ Let's put the values in the formula

↝  F + V  = E + 2

↝  18 + 10 = E + 2

↝  28 = E + 2

↝  E = 28 - 2

↝  E =  26

∴ The Value of E is 26
