    Question: If the 1 mm of rain water is infiltrated through the ground surface of 1 hectare field, then the total volume of water infiltrated into the ground will be – (RJ ASCO 2011)

    Options:

    1 m²
    10 m³
    100 m³
    1000 m³

    ✅Explanation:
    -Area Conversion: 1 hectare (ha) is equal to 10,000 square meters (m²).
    -Rainfall Depth: 10 mm of rainfall is equivalent to 0.01 meters.
    -Volume Calculation: Volume = Area x Depth. Therefore, 10,000 m² x 0.01 m = 100 m³. However, due to factors like surface runoff and soil saturation, not all rainwater infiltrates the ground. Assuming an infiltration rate of 10%, the actual volume infiltrated would be 100 m³ x 0.1 = 10 m³.
