A triangular prism has a triangular cross-section with base cm and perpendicular height cm. The prism is cm long. What is its volume?
Answer and explanation
Correct answer: D. 120 cm
- Step 1: Area of the triangle cm.
- Step 2: Volume area of cross-section length cm.
Answer
120 cm.
Why not the others: 240 cm: This uses base height for the triangle, missing the half. 60 cm: This halves the volume a second time. 12 cm: This is only the area of the triangular end, with no length included.
