Question

verify Euler formula of triangular prism

Answer 1

 Recall the Euler’s formula, F + V = E + 2 Here number of faces, F = 5 Number of vertices, V = 6Number of edges, E = 9 Consider, F+V = 5 + 6 = 11 E + 2 = 9 + 2 = 11 Hence F + V = E + 2 Thus Euler’s formula is verified

Answer 2

Answer with Step-by-step explanation:

As we can see in the attached figure

Number of faces (F) =5

Number of edges (E)= 9

Number of vertices (V) =6

Now Euler's  formula states that V + F - E = 2

So, for triangular prism we have

L.H.S. ⇒ V + F - E = 6 + 5 - 9 = 11 - 9 = 2 = R.H.S.

Thus it verifies the Euler's  formula
