Question

How do you measure the volume of an irregular shaped object that absorbs water?

Answer 1

let the object first absorb water then extract the absorbed water then pour the water to a graduated cylinder then see the volume............

Answer 2

is it something like a sponge?

then id try this: take a bucket measure the amount of water in it soak the the object till it cant absorb anymore water, take the object outs there and  measure how much water is left that should give u the answer.

is it something like salt that dissolves in water?

just use some other liquid which does not get absorbed or dissolves your object  

Answer 3

Wiki says "The volume of any solid, liquid, gas, plasma, vacuum or theoretical object is how much three-dimensional space it occupies, often quantified numerically."

So what I would do is, soak that object till it can absorb no more water. Then, I squeeze it (or whatever) to get the water out. Then I measure how much water was soaked up. That's the volume--how much space it occupies.  

Answer 4

Step -1 First of all cover the material with a non absorbent film or coating fully.

Then immerse the same in known quantity of water and measure the displacement level. This is Vol of Object + coating = V2

Step-2

Remove the coating carefully and place the same in water to find out dispalcement level . This is Vol of coating  V1  

The volume of object will be V = V2 - V1

Answer 5

If an object absorbs water, its "volume", meaning the total space occupied by its edges, will often increase as it absorbs more (such as with a sponge, which is made of elastic material).

To measure the volume of only the non-water material, simply submerge it in water and measure the displacement once all of the air has been removed (in the case of a sponge, squeeze it underwater to get all the air out).

If you want the volume of the object once it has expanded and absorbed water, take the displacement as described above and add it to the volume of the water that you get when you take the fully-soaked sponge and wring it out.
