Q

How do u calculate the density of an irregular object ?

A

You put it on a mass balance to find the mass , then you tie a string around your object and put it into an overflow can.the amount of water that spills out into your graduated cylinder is the volume. Then you divide the mass by the volume which will give you the density.
