A farmer in Gujarat irrigates a 3‑hectare cotton field using a sprinkler system that supplies water at a rate of 2.5 m³ per minute. He operates the system for 6 hours each day. How many cubic metres of water does he use per day?
Answer
900 m³
The correct answer is 900 m³ — Thus the farmer uses 900 m³ of water per day.
Step-by-step solution
- Convert the operating time to minutes: (6 \text{ h} \times 60 \text{ min/h} = 360 \text{ min}).
- Multiply the minutes by the flow rate: (360 \text{ min} \times 2.5 \text{ m}^3/\text{min} = 900 \text{ m}^3).
- Thus the farmer uses 900 m³ of water per day.
Common mistake: Mis‑multiplying hours by minutes or using the field area to calculate water volume
Concept tested: Irrigation water requirement
