# Volume of Void

Written by Jerry Ratzlaff on . Posted in Geotechnical Engineering

Volume of void, abbreviated as V_v, is the ratio of total volume of soil minus volume of solid soil.

## Volume of Void formula

$$\large{ V_v = V_t - V_s }$$
Symbol English Metric
$$\large{ V_v }$$ = volume of void $$\large{ft^3}$$ $$\large{m^3}$$
$$\large{ V_t }$$ = total volume of soil $$\large{ft^3}$$ $$\large{m^3}$$
$$\large{ V_s }$$ = volume of solid soil $$\large{ft^3}$$ $$\large{m^3}$$
