Pour some water into a measuring cup or a graduated cylinder,measure how much water you have poured into your container.After you have done this,drop the object into your container and see how much water it has displaced.Then subtract the original amount of water from the amount of water displaced and your answer should be the volume of the object(This procedure is called Water Displacement,sort of obviously).
Density is weight divided by volume. Measure the weight (with a scale), calculate the volume (which is easy to do if the foam is rectangular in shape - you might even want to cut out a rectangular piece, if your foam has an irregular shape), and divide the weight by the volume.
Measure the volume of the water you have. Insert irregular solid. Measure the volume of the water you have now, and subtract the initial water volume from the new water volume. The difference in volumes is the volume of your irregular solid.
Liquids have a definite volume but no definite shape. You can measure the volume easily by pouring a liquid into a graduated container. But as for its shape, it simply adopts the shape of whatever you pour it into.
Density = (mass) divided by (volume)regardless of the substance, or the shape of the sample.
Amoeba is irregular in shape because it has no bones

To measure volume of large irregular shaped objects you need a displacement can

use calculus and integrate or fill it with water and measure.
because the shape has no correct sides.
If the shape is a regular polygon or curve there are formula for each shape. If the shape is irregular you will have to measure each piece of the shape's edge and sum all the pieces together.
An irregular volume is something and anything that no one can actually measure. An example of this is a cylinder with a cone as its end; a complex equation is needed just to describe the shape that it has.
There are several methods of measuring an irregular shape's volume.Filling it with a known volume of a substance until full.Summing up the Mathematical calculation of sections.
Volume of irregular or regular shape object is the space reserved by the object in any medium.
To obtain the density you need to know the mass, and the volume of the object.So you'd have to weigh it using a balance to obtain the mass.The easiest way to measure the volume (particularly if it's an irregular shape) would be via the displacement of water.density = mass / volume
The unit used to measure irregular volume is cubic centimeters (cm3). However, liters may be used - 1 cm3 is equal to 1 milliliter.
