What is volume? — Volume definition
Volume is the amount of space that an object or substance occupies. Generally, the volume of a container is understood as its capacity — not the amount of space the container itself displaces. Cubic meter (m3) is an SI unit for volume.
However, the term volume may also refer to many other things, such as
the degree of loudness or the intensity of a sound;
the number or amount of something (usually large quantity); and
formal word for a book or one in a set of related books.
