To find the volume of an irregular solid using the overflow can method, you would first fill the overflow can with water and measure the initial volume. Next, you would submerge the irregular solid in the overflow can, causing the water to overflow. Measure the new volume of water in the overflow can with the solid submerged. Finally, you would subtract the initial volume from the final volume to find the volume of the irregular solid.
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!
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.
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.

You place it in water to see the volume of water it displaces. Fill a large, graduated measuring cylinder to about halfway with water (say to 50mL) Put the irregular solid in, and measure the volume it reads (solid + water). (say it reads 80mL) So the volume of the irregular solid will be: volume(solid+water) - volume(water). For example, the volume of the water was 50mL, and when the solid was added, the volume increased to 80mL. The volume of the solid would be 80mL - 50mL. So it would be 30mL.

Finding the mass of an irregular solid before finding its volume allows for the mass to be determined without altering the shape or structure of the object. This preserves the accuracy of the mass measurement because irregular shapes may not easily fit into standard volume measuring equipment. Additionally, knowing the mass can help determine the most appropriate method for measuring the volume of the irregular solid.
To find the density of a rectangular solid object, you would calculate the mass of the object by multiplying its volume by its density. For an irregular solid object, you would typically measure its mass using a balance and its volume using displacement of water, then divide the mass by the volume to find the density. The main difference lies in how you determine the volume of the object, with rectangular solids having a straightforward formula for volume calculation compared to irregular shapes which require more complex methods.
When you are measureing smaller units you would use mL
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!
To measure the solid volume of an irregular object, you can use a graduated cylinder filled with water. By submerging the irregular object in the water, you can measure the change in water level, which corresponds to the object's volume. Alternatively, you could use a displacement method with a volumetric flask or a beaker, ensuring that the object is fully submerged for an accurate measurement.
To measure the volume of a solid, you would place the solid in a graduated cylinder or beaker (depending on the size of the solid) with a recorded volume of water. After putting the solid in the water, the water will rise, and subtracting the original volume from the final volume will give you the volume of the solid. Ex. Put a block in a graduated cylinder with 50 mL of water and the level rises to 75 mL. Volume=75-50=25 mL To determine the mass of the solid, you would simply mass it on a balance or scale.
The fact that a solid is irregular has nothing to do with which unit you pick. It is the size of the object which determines this. If it is the size of a room you might use metres cubed, but if it would fit in your pocket then centimetres cubed will be more appropriate. It is the method of measuring the volume which is affected by the irregularity. You can't do it with measuring and geometry, so you have to use the displacement of water.
