A farmer cultivates 3 hectares of wheat. The water requirement of wheat is 1,500 mm per season. Calculate the total volume of water (in cubic metres) required for this crop for one season.
Answer
45,000 m³.
The correct answer is 45,000 m³. — Multiply area by depth: 30,000 m² × 1.5 m = 45,000 m³.
Step-by-step solution
- Convert area to square metres: 3 ha = 30,000 m².
- Convert rainfall depth to metres: 1,500 mm = 1.5 m.
- Multiply area by depth: 30,000 m² × 1.5 m = 45,000 m³.
Common mistake: Converting hectares to m² incorrectly.
Concept tested: Water requirement calculation.
