PlanetPhysics/Volume

Volume is a property associated with a finite region of space. The volume occupied by a given region of space $$\Omega$$ is typically denoted by the symbol $$V$$. It is always possible to subdivide a given region into smaller sub-regions. The symbol $$dV$$ is often used to denote the volume occupied by an arbitrarily small region of space. Thus the total volume occupied by $$\Omega$$ can be expressed as: $$ V = \int_{\Omega} dV $$
