In a shower, 5 cm of rain falls. What is the volume of water that falls on 2 hectare area of land?
- A. 100 cubic metre
- B. 1000 cubic metre ✓
- C. 4000 cubic metre
- D. 10000 cubic metre
Correct Answer: B. 1000 cubic metre
Explanation
Area = 2 \text{ hectares} = 2 \times 10000 = 20,000 \text{ m}^2. Depth of rainfall = 5 \text{ cm} = 0.05 \text{ m}. Volume of water = \text{Area} \times \text{Depth} = 20,000 \times 0.05 = 1000 cubic metres.
