Question

12. Verify Euler's formula for:-
(i) Square pyramid.
(ii) Triangular prism.
(iii) Rectangular prism.​

Answer 1

Step-by-step explanation:

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 = 11Hence F + V = E + 2 Thus Euler's formula is verified.

Answer 2
