Volume is the quantification of the three-dimensional space a substance occupies. The SI unit for volume is the cubic meter, or m 3. By convention, the volume of a container is typically its capacity, and how much fluid it is able to hold, rather than the amount of space that the actual container displaces. Volumes of many shapes can be calculated by using well-defined formulas. In some cases ...
