After a soil was saturated with water, you measured the total volume and pore space of your soil as 400 cm3 and 220 cm3, respectively.  Assuming you had 100%, 50%, and 20% saturation of the pore space as the soil dried, calculate the volume of air, water, and the solid at 100%, 50%, and 20% saturation of the pore space?
