1 : the degree of loudness or the intensity of a sound also : loudness. 2 : the amount of space occupied by a three-dimensional object as measured in cubic units (such as quarts or liters) : cubic capacity — see Metric System Table, Weights and Measures Table.
How do you explain volume?
Volume refers to the amount of space the object takes up. In other words, volume is a measure of the size of an object, just like height and width are ways to describe size. If the object is hollow (in other words, empty), volume is the amount of water it can hold. Try this at home: Take a large cup and a small cup.
Why is volume important in math?
Finding the volume of an object can help us to determine the amount required to fill that object, like the amount of water needed to fill a bottle, an aquarium or a water tank. The volume of an object is measured in cubic units such as cubic centimeters, cubic inch, cubic foot, cubic meter, etc.
What is the difference between disk and volume?

A volume is a logical assembly of one or more partitions that is mounted by the operating system for use as a mass storage container.
What is new volume storage?
The New-Volume cmdlet creates a volume with the specified file system.
