Question

Verify the Euler's formula for any three prisms and pyramids.

Answer 1

Consider the triangular prism shown Recall the Euler’s formula, F + V = E + 2 Here number of faces, F = 5 Number of vertices, V = 6 Number 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.
