? 1 hectare = 10000 m2
⇒ Area of field = 4 hectare = 4 × 10000 = 40000 m2
Height of rainfall = 8 cm = 0.08 m
⇒ Volume of water that fell on field = Area of field × Height of rainfall = 40000 × 0.08 = 3200 m3
? 1 m3 = 1000 L
∴ Volume of water that fell on field = 3200 × 1000 = 3200000 L
⇒ Area of field = 4 hectare = 4 × 10000 = 40000 m2
Height of rainfall = 8 cm = 0.08 m
⇒ Volume of water that fell on field = Area of field × Height of rainfall = 40000 × 0.08 = 3200 m3
? 1 m3 = 1000 L
∴ Volume of water that fell on field = 3200 × 1000 = 3200000 L
