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.
The base unit for an irregular solid is typically cubic centimeters (cm^3) when measuring volume. This involves calculating the volume by either submerging the solid in water and measuring the displacement, or using mathematical formulas that approximate the shape of the object.
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.
To find the volume of an element, calculate the product of its length, width, and height if it is a rectangular shape. If the element is a cylinder, calculate the volume using the formula V = πr²h, where r is the radius and h is the height. For irregular shapes, use integration or approximation methods to find the volume.

One way to find the volume of a large irregular shape object is to use the displacement method. Submerge the object in a container of water and measure the volume of water displaced. This volume is equal to the volume of the irregular object.
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.
To find the density of an irregular shape, you will first need to measure its mass using a scale. Next, you will need to find the volume of the shape, which can be done by water displacement method or by using a formula suitable for the shape. Finally, divide the mass by the volume to calculate the density of the irregular shape.
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.
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.
To find the density of an irregular shape, you would first measure its mass using a scale. Then, you would need to measure its volume using a displacement method or by using water displacement. Once you have both the mass and volume, you can calculate density by dividing the mass by the volume.
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.
