DefinitionMeaning of Capacity and Volume Capacity and volume are terms mostly used for the measurements to describe the amount of space occupied by the three dimensional object. Usually, capacity refers to the ability of a container or vessel to hold a certain volume of liquid or mass, and volume is particularly the amount of space occupied by a three-dimensional body. Some examples of engineering, manufacturing, architecture, and fluid mechanics problems which require capacity and volume calculations are designing structures and containers, and calculating the quantities of materials to subsequently store or transfer. Eg: Volume of a cylinder, V = πr2h, where r is the radius, h is the height of the tank
