Answer: B - The degree of saturation of a 600 cm³ soil sample with the given volumetric values is 64.3%.

Solution: Use the following equation to determine the degree of saturation, S.

S = volume of water / volume of voids

= V_w / V_v

Given V_v = total volume - volume of solids

V_v = 600 - 320 = 280 cm³

And V_w = V_T - V_v - V_s

V_w = 600 - 100 - 320 = 180 cm³

Therefore S = V_w / V_v = (180 cm³ / 280 cm³) x 100

S = 64.3%
