The easiest way is to use Archimedes principle ! Immerse the object in a container of water that is full to the brim - then collect the displaced over-spill, and measure it.
He discovered the method to calculate the volume of a irregular object (rock).
by a graduated cylinder (don't rely on this answer i am not sure of it)
One way to figure this out is to put the object in a graduated cylinder containing water and measuring the changes in the volume of the water.
By definition, an irregular object is one that does not have an easy mathematical representation, it is extremely difficult (if not impossible) to calculate its volume without placing it into a solution of some sort. Attempts to calculate volume otherwise would be subject to severe rounding error, and would thus make it unsuitable for scientific use. For the very special case where the object is uniform and/or its density, ρ=m/V, is known, then its volume could be determined from its mass, V=m/ρ.
millilitre or litre - depending on size. Or possibly microlitre, kilolitre, megalitre etc.
To calculate the volume of an irregular object you will need a container with meaurements and water. Place the irregular object in your container and fill with water until the entire object is covered. Record volume A. Then remove the irregular object and record volume B. The volume of your irregulare object is equal to volume A minus volume B.
Volume of irregular or regular shape object is the space reserved by the object in any medium.
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.
Volume of irregular or regular shape object is the space reserved by the object in any medium.
method usede to figure the volume of an irregular shaped object
by measuring the object
The volume of the object.
== == Water Displacement
...V1xV2....
By placing the object in water and the volume of water displaced is equal to the volume of the object immersed
[object Object]
Irregular solid volume is still measured in cm3 etcTo Find the Volume of an irregular object you can,Measure out a proportional amount of water to the object you are finding the volume ofPut the object in the container of waterSee how much the water has risen byYou now have the volume!!(The difference between the new and old volumes of water is the volume
