**volume**of any solid, liquid, plasma, vacuum or theoretical object is how much three-dimensional space it occupies, often quantified numerically. One-dimensional figures (such as lines) and two-dimensional shapes such as square geometry squares are assigned zero volume in the three-dimensional space. Volume is commonly presented in units such as mililitres or cm^{3}(milliliters or cubic centimeters). - Volumes of some simple shapes, such as regular, straight-edged and circular shapes can be easily calculated using arithmetic Formulas. More complicated shapes can be calculated by Integral Calculus if a formula exists for its boundary. The volume of any shape can be determined by displacement.
- In
*Differential Geometry*, volume is expressed by means of the Volume Form, and is an important global Riemannian invariant. - Volume is a fundamental parameter in
*Thermodynamics*and it is conjugate to Pressure.
