Answer
400
The correct answer is 400 — Answer: 400 litres.
Step-by-step solution
- Convert 10 cm to meters: 0.10 m.
- Compute volume = area × depth = 4 m² × 0.10 m = 0.40 m³.
- Convert cubic metres to litres: 0.40 m³ × 1000 L/m³ = 400 L.
- Answer: 400 litres.
Common mistake: Mixing up meters and centimeters or forgetting to convert cubic metres to litres
