Geometry

Question Analysis:
This models a real tent as a triangular prism and requires using triangle area before finding volume.
The main focus is on correctly applying the prism volume formula in a practical context.

Key Concept Explanation:
Volume = (1/2 × base × height of triangle) × prism length

Step-by-Step Solution:
Triangle area = 1/2 × 2.5 × 2 = 2.5
Volume = 2.5 × 4 = 10 m³
