The volume of gases depends on the volume of their container. That’s because gases
expand to fill whatever space is available to them. For example, as you drink water from a
bottle, air rushes in to take the place of the water. An "empty" liter bottle actually holds a
liter of air. How could you find the volume of air in an "empty" room?
The volume of regularly shaped solids can be
calculated from their dimensions. For example,
the volume of a rectangular solid is the product
of its length, width, and height (l × w × h).
For solids that have irregular shapes, the displacement method is used to measure volume.
You can see how it works in Figure below and in the video below. The SI unit for solid
volumes is cubic meters (m3). However, cubic centimeters (cm3) are often used for
smaller volume measurements.

The displacement method is used to find the volume of an irregularly shaped solid object. It measures
the amount of water that the object displaces, or moves out of the way. What is the volume of the toy
dinosaur in mL?
