# Volume of Voids

## formulas that use Volume of Voids

 $$\large{ V_v = V_t - V_s }$$ $$\large{ V_v = n \; V_t }$$ (porosity) $$\large{ V_v = e \; V_s }$$ (void ratio)

### Where:

$$\large{ V_v }$$ = volume of voids

$$\large{ n }$$ = porosity

$$\large{ V_t }$$ = total volume of soil

$$\large{ e }$$ = void ratio

$$\large{ V_s }$$ = volume of solid soil

$$\large{ w }$$ = water content
