You use water displacement. First you take the volume of the water w/o the object. Then you drop the object in the water and record the volume, subtract the two and you will end up with the volume of the irregualar figure
hope this helped!

Using Calculus: (Mathematically)
Since you are asking for volume it will depend on the shape of the figure to determine how many integrals it will take to find the volume. Either by a single, double or triple integral.
Weigh it if possible: (Physically), if this cannot be done, get some dimensions and use calculus.
-The idea of using water displacement was also a clever way to come up with the exact volume.
Hope this Helps.

Hey there!
It really depends on how you look at it. Some figures can consist of regular figures, where you know the volume of the figures. Others, you have to use theorems.
For example, Cavalieri's Principle can be used to find volumes of oblique prisms and cylinders.
In order to find an exact volume, you need to use calculus.
The formula can be derived from the definite integral.
V=â«pi*x^2 dx, with upper limit r and lower limit -r.
This is the formula to find the exact volume of an irregular figure.
Hope it helps!

If it exists only on paper then you need to calculate the area of a thin slice, then move up a speck to the next slice and calculate its area. Each of those areas multiplied by the thickness of the slice addxs up to the total volume. That is using calculus to sum up (integrate) all of the small volumes to make the total volume.
If it is a real object like a vase you could fill it with water to the top and then pour out the water into a graduated beaker and see what volume the beaker has measured.

An irregular figure is usually made up of multiple regular solids. Just take the sum of all the volumes, and there you have it.

You fill up a container of water and find the measurement, record it. Then drop the object it and find the new volume of the water.
The orginal voume-the new volume is your objects volume

My science teacher told the class calculus.
