Given that 1 Cusec equals 28.3 liters and 1 Cumec equals 1000 liters, what is the volume represented by 1 hectare-millimeter (ha mm)?

Explanation

One hectare is 10,000 square meters, and 1 millimeter of rainfall over 1 hectare corresponds to a volume of 10,000 liters (since 1 mm = 0.001 meters, volume = area × depth = 10,000 m² × 0.001 m = 10 m³, and 1 m³ = 1000 liters, so total volume = 10,000 liters or 10^4 liters). Therefore, the correct volume for 1 ha mm is 10,000 liters.
