From Wikipedia, the free encyclopedia
Volume is how much three-dimensional space a substance (solid, liquid, gas, or plasma) or shape occupies or contains,[1] often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container, i. e. the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.
Volume of a Liquid
Solids have defined shapes either regular or irregular. If the shape of a solid is regular, then its volume is calculated by geometrical means and if not, it can be figured out indirectly. In any case, the volume is defined in fixed directions.
However, liquids have no definite shape. They occupy the available space of a container. They spread over the entire the area of section and stands up to a height. Hence the volume of a liquid is the volume of its container up to the height of the liquid level. For this reason, the volume of hollow shapes are called as ‘capacity’ of the shape.This concept is mainly used in measuring volume of liquid.
