If possible, fully immerse the object in water, and measure the volume of displaced water.
The volumes of small irregular solids are usually easily measured by measuring the volume of fluid displaced when they are immersed in a liquid. For example: You would have to put the object in a measuring glass with water in it. (~1/3 filled) Put the object in it and then get the number from the measuring glass (beaker etc. mostly beaker) and that is how you measure a irregular solid!
Put water in the cylinder to a level that would cover the object. Drop the item in and if it sinks, read the new level on the graduations. The difference in volume between the two marks, is the volume of the item.
Immerse the object in water and measure the volume of water that is displaced. One way would be to fill a container, large enough to hold the object, with water until it is just about to overflow. The container and water would need to be inside another container that could capture the displaced water. Submerge the object in the water and then measure the volume (or weight) of the water that overflows
Because, from Archimedes' Principle, the volume of the water displaced is equal to the volume of the object displacing it. So, were you to collect all the displaced water and put it into a graduated cylinder, it would tell you the volume of the object in question.
Displacement
I would place it in a container full of liquid after measuring the liquid. I would measure the amount of liquid displaced by the object. That amount is equal to the volume of the irregular object if it is fully submerged in the liquid.
For an irregular shaped object that cannot be measured and then volume calculated with a formula.
To find the density of an irregular shaped object that sinks, you would need to measure its mass using a balance and measure its volume by water displacement method. Divide the mass of the object by its volume to calculate its density.
If possible, fully immerse the object in water, and measure the volume of displaced water.
To find the density of an irregular object, you would first measure its mass using a scale. Next, you would find the volume of the object using displacement method or by calculating it with water displacement. Divide the mass by the volume to calculate the density of the irregular object.
To find the density of an irregular object, you would need to measure its mass using a scale, and then calculate its volume using a displacement method or by measuring dimensions and using a formula. Once you have both values, divide the mass by the volume to determine the density of the irregular object.
One way to calculate the volume of an irregular object is through the water displacement method. Fill a container with a known volume of water, then submerge the irregular object and measure the increase in water level. The difference in water level represents the volume of the object.
To find the volume of an irregular object using water displacement, you need to first measure the initial volume of water in a container. Next, carefully submerge the object in the water and measure the new volume of water. The difference in water volume before and after submerging the object is equal to the volume of the irregular object.
To find the density of a regular shaped object, you can calculate it by dividing the mass of the object by its volume. For irregular shaped objects, you would measure the mass of the object using a scale, then measure its displaced water volume when submerged in a graduated cylinder. The density can then be calculated by dividing the mass by the volume of water displaced.

To calculate the density of an irregular shaped object like a key, you would first measure its mass using a scale. Next, you would measure its volume using a displacement method with water. Finally, you would divide the mass of the key by its volume to determine the density.
