Irregular solid volume is still measured in cm3 etc
To Find the Volume of an irregular object you can,
You now have the volume!!
(The difference between the new and old volumes of water is the volume
The water displacement method is typically used to find the volume of an irregular solid. The object is submerged in a known amount of water, and the increase in water volume is measured. This increase in volume is equal to the volume of the irregular solid.

Fill the can to the overflow level with water.Very gently lower the irregular solid into the can and make sure to catch all the overflow.Measure the volume of overflow.That is the same as the volume of the irregular solid.Warning! This method will be a total disaster if the solid is soluble in water. You could try any other liquid instead.

The best way to find the volume of an irregular solid is to submerge it in a liquid and see how much the liquid rises. You can also use calculus and tripple integrals, but that gets really sticky.
When you need to find volume of an irregular solid or a liquid.
The unit for volume is the same, whether the shape is regular or irregular.
When you are measureing smaller units you would use mL
You can measure the volume of irregular solids by using water displacment which is meausured in mililiters (mL), and that, in turn, can be converted to cubic centimeters (cm3)

It's simple, you just have to take a measurable recipient big enough to contain the solid, fill the recipient with a known volume of water and drop the irregular solid into the water. Then you can measure the increase of volume, which will be equivalent to the volume of your solid.
You place it in water to see the volume of water it displaces. Fill a large, graduated measuring cylinder to about halfway with water (say to 50mL) Put the irregular solid in, and measure the volume it reads (solid + water). (say it reads 80mL) So the volume of the irregular solid will be: volume(solid+water) - volume(water). For example, the volume of the water was 50mL, and when the solid was added, the volume increased to 80mL. The volume of the solid would be 80mL - 50mL. So it would be 30mL.
The fact that a solid is irregular has nothing to do with which unit you pick. It is the size of the object which determines this. If it is the size of a room you might use metres cubed, but if it would fit in your pocket then centimetres cubed will be more appropriate. It is the method of measuring the volume which is affected by the irregularity. You can't do it with measuring and geometry, so you have to use the displacement of water.
Volume is measured in any cubic unit, such as cubic meter, cubic decimeter (also known as liter) or cubic centimeter (also known as milliliter).
