alleryA prism has n-sided bases (n ≥ 3). How many vertices and edges does it have?
An vertices; 2n edges
B2n vertices; 2n edges
Cn + 1 vertices; 2n edges
D2n vertices; 3n edges
Answer & Solution
Correct answer: D. 2n vertices; 3n edges
The two bases contribute 2n vertices and 2n edges, and n joining edges give 3n edges altogether.
