Question
Verify Euler's formula for the following polyhedrons:

Answer

In the given polyhedron: Edges $E = 21$ Faces $F = 9$ Vertices $V = 14$

Now, putting these values in Euler's formula: $LHS: F + V = 9 + 14 = 23$
$RHS: E + 2 = 21 + 2 = 23$ This is true.
​​​​​​​Hence, Euler's formula is satisfied.
