How do you find the volume of an irregular object that dissolves in water?

Question

aside from using oil, kerosene, powder, etc. to replace water?

Answer 1

Wrap the object with a plastic first

Answer 2

Mass / Density = Volume

Answer 3

Use displacement- wrap it in plastic first so it doesn't dissolve if you are using water to determine the displacement.

1) wrap item in plastic to protect it from water.

2) put water into a vessel that has volume measures.

3) take note of initial volume of the water.

4) Submerge item in water.

5) take note of final volume after item is submerged.

6) Subtract initial volume from final volume to determine items volume

Answer 4

Measure by the density
