Question

A soil 80 cm deep has a volume water content = 0.12. Find out the quantity of water that must be added to bring the volume water content to 0.30.

• A. 9.6
• B. 24.0
• C. 14.4
• D. 18.4

Hint:

To solve this in one step: subtract the initial water content from the final content ($0.30 - 0.12 = 0.18$), and multiply this difference directly by the soil depth ($0.18 \times 80\text{ cm} = 14.4\text{ cm}$).
