Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the void ratio if the volume of voids is 10 m³ and the volume of soil solids is 5 m³?
💡 Hint: Use the formula e = Vv / Vs.
Question 2
Easy
If a soil has a total volume of 100 m³ and 40 m³ of voids, calculate the porosity.
💡 Hint: Use the formula n = Vv / Vt * 100.

Challenge Problems
Push your limits with challenges.
Question 1
Given a soil sample with a total volume of 100 m³, where the volume of voids is 30 m³, how does varying saturation level impact the air voids percentage?
💡 Hint: Evaluate how the volume of water changes with saturation levels.
Question 2
A soil has a void ratio of 2.0 and this sample contains 25 m³ of solids. Calculate the total volume and then determine the total voids.
💡 Hint: Revisit the void ratio definitions to facilitate calculations.
