A natural made rock
Weigh the object. Determine the volume. Divide the mass by the volume to get the density. To get the volume of an irregular shaped object can be challenging especially if there are cavities (holes) in it. submersion in a liquid or powder of known volume might be possible. Measure the difference in the volume of the liquid and the liquid + the object (making sure the object is entirely below the surface of the liquid and that any cavities are filled).
To measure volume of large irregular shaped objects you need a displacement can
A measuring cup or graduated cylinderWater or other liquid to place the solid in
You need to find the displacement, easiest way for irregular objects is water displacement. If it can fit in a graduated cylinder use that and find out how much water is displaced when the object is submerged. Then weigh it and divide the weight by the volume. Your unit will be whatever units you weighed it in, say grams, per whatever unit you measured displacement in, say cm.
The same units are used for regular or irregular objects - for example, kilogram per cubic meter.
I am not positive but i think that a regular shaped object can be measured and an irregular can not Hope this helps :D
Base x Height X Length= Volume
A 6 sided hexagon can be a regular or an irregular shaped polygon
A natural made rock
regualr shaped

Density = (mass) divided by (volume)regardless of the substance, or the shape of the sample.

The eureka beaker is a beaker to find out the density of irregular shaped objects. Archimedes invented it when he stepped into his bath and saw that the water level rose. He shouted "Eureka!" which means "i have found it!".

Octagons can be irregular or regular. It depends on the measure of the angles and the length of a side. An octagon is a shape with 8 sides, not necessarily the regular octagon that stop signs are shaped like.
