Answer
375000 litres

The correct answer is 375000 litres — 2. Convert cubic metres to litres: 1 m³ = 1000 litres, so 375 m³ = 375 × 1000 = 375000 litres.

Step-by-step solution

  1. 1. Find volume in cubic metres: 50 m × 5 m × 1.5 m = 375 m³.
  2. 2. Convert cubic metres to litres: 1 m³ = 1000 litres, so 375 m³ = 375 × 1000 = 375000 litres.
Common mistake: Skipping the conversion from cubic metres to litres or mis‑multiplying dimensions

Concept tested: Volume of water bodies
