A soil sample has a total volume of 0.020 cubic metres and a volume of solids of 0.012 cubic metres. Its void ratio is:
Correct answer: C. 0.67
- A. 0.40
- B. 0.60
- C. 0.67
- D. 1.67
Explanation
The volume of voids is 0.020 minus 0.012, which equals 0.008 cubic metres. Void ratio equals volume of voids divided by volume of solids, giving 0.008 divided by 0.012, or approximately 0.67.

About Soil Mechanics and Foundations
Soil mechanics examines index properties, phase relationships, classification, permeability, seepage, compaction, consolidation, shear strength and earth pressure. Foundations apply these principles to bearing capacity, settlement and shallow or deep foundation selection, with clear distinction between compaction, which expels air, and consolidation, which expels water over time.
