use a graduated cylinder
Measure the displacement of water when the object is submerged in water. This gives the volume ; then weigh the object and divide the weight by the volume to get the density.
An irregular shape can be called a blob.
Volume of irregular or regular shape object is the space reserved by the object in any medium.
If you can somehow describe the shape, a popular tool is integration. This means that you imagine cutting the object into thin slices, calculate the volume of each slice, then add everything up.(And if the slices have an irregular shape, they, in turn, are cut into thin strips - so you would be using a double integral.)
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.
use a graduated cylinder
Density = (mass) divided by (volume)regardless of the substance, or the shape of the sample.
The shape of an object is not enough to calculate its density. You also need its mass and then Density = Mass/Volume.
use calculus and integrate or fill it with water and measure.
A square is not an irregular shape and conversely. So the square of an irregular shape cannot exist.A square is not an irregular shape and conversely.

There is no set formula.You have to "split" the irregular shape into regular shapes, use whatever dimensions you have and fit them into the formulas of the known shapes.Find the area of each split shape. Lastly, you add all the areas to give you the totl area of the irregular shape
The shape does not affect the density: density = mass / volume = 50.2g / 5.0 ml = 10.04 g/ml
Mass divided by volume, just like anything else.
Finding the area of an irregular shape is now quite easily done after watching the instructional video at [See related link below for the website] and it's for free
An irregular shape!
You break it up into smaller shapes which are less irregular. If these are more regular, you can calculate their contribution to the perimeter, and their area. You can then add these together.
