Consider the net figure of a rectangular pyramid:
Let the number of edges be E and number of vertices be V (in the 2-D figure: take edges as the intersection lines and vertices as intersection points of the lines).Then the value of E + V is 24. True/False?
False
From the figure,
Number of edges (E) = 12
Number of vertices (V) = 8
Hence, E + V = 20.
