Volume

Volume is the amount of 3-dimensional space occupied by an object, substance, or closed surface. For example, think of the space an apple would take up in a bag. The remaining volume of the bag is the amount of space left in the bag after subtracting the volume of the apple.

Units of volume

The volume of an object can be calculated from its 1-dimensional parameters, such as length, width, and height.
