Calculate the volume required per ha if 2 lit water is needed to spray 70m length with a swath of 1.4 m.

Solution (By Examveda Team)

To calculate the volume required per hectare (ha) for spraying, we need to find the area covered by one swath and then multiply it by the number of swaths required to cover one hectare.
Area covered by one swath = length × swath width = 70 m × 1.4 m = 98 m²
To cover one hectare (10,000 m²), we need to divide the total area by the area covered by one swath:
Volume required per hectare = (Area of one hectare) / (Area covered by one swath) × Volume for one swath
Volume required per hectare = (10,000 m²) / (98 m²) × 2 L = 204.08 L
Rounding off 204.08 to the nearest whole number gives 204 L. So, the correct answer is indeed Option B: 204 L.
