1. 1.

   What is the unit for measuring density?

   Hint

   Think about mass divided by volume.

2. 2.

   What happens to water content in a dry soil?

   Hint

   Remember, dry means lacking water.

3. 3.

   What is the unit used to measure density?

   • g/cm³
   • ton/m³
   • All of the above

   Hint

   Think of mass divided by volume.

4. 4.

   True or False: The water content can exceed 100%.

   • True
   • False

   Hint

   Consider what happens in saturated conditions.

5. 5.

   You are given a soil sample with a mass of 2400 kg and a volume of 1.5 m³. Calculate the density.

   Hint

   Use the density formula.

6. 6.

   Explain how the specific gravity of a soil affects its use in construction.

   Hint

   Think about soil behavior under pressure.
