Volume is the amount of 3-dimensional space that an object occupies. The SI unit for volume is cubic meters (m3)
It is called the density.
The volume of an object is measured in units3 because it measures the 3 dimensions of the length, height, and width of an object. However, the units themselves are subject to change. For example it could be centimeters3, inches3, feet3, or any other units of measurement cubed.
cubic units
Metric units of volume include the cubic meter, cubic centimeter, cubic millimeter, milliliter, cubic kilometer, and liter. When used to express the volume of a space or object, the shape of the object is completely irrelevant.
It is used to find the volume of an irregularly shaped object. An object dropped into a volume of water will displace an equal volume of water.
Units can't be used to find an object's mass. To do that, you need equipment such as a scale or beam balance. Once you have found the object's mass, you use units to describe it, and to tell other people about it. There are several units of mass currently in use. Some of them are: -- kilogram -- gram -- milligram -- microgram -- nanogram -- metric ton -- pound-mass -- slug
