Q: The volume of voids Vv is equal to the sum of
  • A. the volume of air and volume of solids
  • B. the volume of air and volume of water
  • C. the volume of water and volume of solids
  • D. the volume of water and the weight of water
Correct Answer: Option B - Volume of voids is equal to the sum of volumes of air and water. For a dry soil, it becomes the weight of solids itself. But the volume of air can not be ignored. Volume of voids has a greater influence in soils compared to any other.
