alleryFind the total number of edges of a hexagonal prism.
A14
B12
C24
D18
Answer & Solution
Correct answer: D. 18
1. Each hexagonal end has 6 edges, which is 12 edges for the two ends.
2. Six more edges join the two hexagons.
3. So 12 + 6 = 18 edges.
4. Check with Euler: faces 8 + vertices 12 - edges 18 = 2.
