A soil has a void ratio of 4. If the soil's specific weight is 18 kN/m3, calculate the volume of voids and the volume of solids in a 1 m³ soil sample.
💡 Hint: Use the formula: V_v = e * V_s.
Analyze how a void ratio change from 0.3 to 0.6 might impact the drainage capability of a building site over time.
💡 Hint: Reflect on soil behavior under increased permeability conditions.
