Question

19. Verify Euler’s formula for these solids:

Answer 1

$\huge \mathfrak{ \red{ \underline{Solution} : }}$

(i)ANSWER :↓

Faces = 7

Sides = 15

Vertices = 10

Euler’s formula: F + V – E = 2

⇒ 7 + 10 – 15 = 2

⇒ 2 = 2

Hence, Euler’s formula is verified✔.

(ii) ANSWER:↓

Faces = 9

Sides = 16

Vertices = 9

Euler’s Formula: F + V – E = 2

⇒ 9 + 9 – 16 = 2

⇒ 2 = 2

Hence, Euler’s formula is verified✔
