How many edges does a triangular prism have?
Answer and explanation
Correct answer: B. 9
- Step 1: There are 3 edges on each triangular end, which is 6.
- Step 2: There are 3 edges joining the two ends.
- Step 3: 6 + 3 = 9.
Answer
9.
Why not the others: 6 counts only the two triangles, 8 miscounts and 12 is the number of edges on a cuboid.
