What Is the Scientific Definition of Volume?
In scientific terms, volume is three-dimensional space occupied by a gas, liquid or solid. Scientists measure volume in cubic units, such as liters, cubic meters, gallons and ounces. The most common equation to find volume is mass divided by density.
It is important to be able to find the volume of shapes for many different scientific calculations. Not only does volume act as an accurate measurement of what is in a container, it also helps determine pressure and concentration. In geometry, to figure out the volume of a rectangle, take the measurements of all of its sides, and multiply them together.
