Generally, soil can be divided to three constituent phases in natural occurrence. It consists of solid (soil particle), liquid (water) and gas (air) which naturally intermixed. In soil mechanics, these phases were representing in unit solid volume soil model. Sketch the soil model in detail with the various mass and volume dimensions.
