How do you measure the volume of an irregular shaped solid object?

if the object doesnt float, just immerse it in a known amount of water and measure the displacement.





if the object does float, attach it to a very dense object of known volume and measure the water displacement, subtracting the volume of the very dense object.How do you measure the volume of an irregular shaped solid object?
Measure the height of water in a container of known cross-section. Sink the solid in the water, and measure the height again. The change in the indicated volume of the water, is the volume of the solid.





How do you measure the volume of an irregular shaped solid object?
Immerse it completely in water and measure the volume of water displaced, either by increase in water level in a cylindrical jar of known area, or the measuring water spilled when immersed in jar filled to the brim.
Use water displacement and a graduted cylinder.





Measure the water in the cylinder, then add the object.





Look at the water level again. Subtract the first measurement from the second and there you have the volume of the object.





Got it?
Submerge it in a measured volume of water. Note the new measure of volume, subtract the new from the initial volume and you will have the volume of the object.
Immersing it in water, and measuring the amount of water displaced , Archimedes did it thousands of years ago ;-)
Drop it water and measure displacement



Do you know the density? If not you could just drop the object in a beaker of water and measure the displaced fluid.
Put it in water.
break it up into regular shapes and add them
