What is the weight of water (in metric tonnes) of annual rainfall falling there on a hectare of land?
Consider the following for the next two (02) items that follow :<br>The annual rainfall at a place is 40 cm. The weight of water is 1 metric tonne per cubic meter.
- A. 40
- B. 400
- C. 4000 ✓
- D. 40000
Correct Answer: C. 4000
