Ideal Gas Law:
PV = nRT
P is pressure
V is volume
n is number of moles of the gas
R is the universal gas constant
T is the absolute temperature of the gas

Steve S has the right idea with the Ideal Gas Law:
PV = nRT
P is pressure
V is volume
n is number of moles of the gas
R is the universal gas constant
T is the absolute temperature of the gas
You can rearrange it to be
V = nRT/P
So if you know n, R, T & P you can calculate the volume.
But notice the important part: Volume of a gas depends on the temperature and pressure. If temperature goes up/down, so does the volume - which is why many gases are shipped very cold.
If the pressure goes up, the volume goes down (and vice versa).
This is why when we fill a canister of gas with a lot of gas (lots of volume squished into a small volume) the pressure goes up.

Ideal Gas law. refer to other answers.
If we knew more about the circumstances, a more definite answer might ensue. The container of my air compressor is constant. I always know the volume. The pressure varies. I read the gage to find the pressure.

The same way you get the volume of a liquid.

There are many ways. It can be calculated and it can be measured. I'm sure your textbook explains it.
