Below is a method you can use when measuring relatively small objects.
Firstly, you can pour a known amount of water into a measuring cylinder. Next place the object into the water and ensure that it is completely submerged. Note the increase in the height of the water and its coresponding volume marking. The increase in volume from the original volume of water is the volume of the object.
You can use a displacement can instead of a measuring cylinder to make you result more accurate.
1) obtain a measuring jug with a scale which is large enough to fit the object.
2) fill the jug 1/2 full with water and read off how much water is in the jug.
3) place the object in the water filled jug and read off where the water now comes to in the jug. (Note: the water must cover the object, if it does not go back a step an put more water in the jug to start with)
4) subtract the first measurement from the second and this will be the volume of the object.
If the object is small enough to fit completely inside a container and will not be damaged by or absorb water, place the object inside the container and fill the container with water until the water level is at the top of the object. Move the object, rotating it if necessary, to ensure that no air bubbles are trapped in any irregular surfaces. Mark the water level inside the container with a grease pencil or piece of tape, then remove the object. Using a graduated container such as a beaker or measuring cup, keeping track of the amount of water used, fill the container with water until the water level reaches the mark. The volume of water added will equal the volume of the object.
I don't have the equations handy, but I figured out a way using air pressure. Imagine having two air tight containers (large enough to hold the object in question). Connect them with a piece of tubing with a valve. Close the valve and pressurize the container without the object in it (measure the pressure via pressure gauge manometer). Now, open the valve between the two containers and measure the final pressure of the system once it equalizes. The larger the object is, the smaller the pressure drop. The volume should be calcuable using the ideal gas law (PV=nRT).
Use fine sand instead of water. Add the sample to the container, and a volume X of sand to the container until the sample is covered. Level the sand and measure the volume Y. The volume of the sample is V = Y - X.
Immerse it in water and the volume of water displaced is equal to the volume of the object in the water.
The pieces are then dipped in a cup full of liquid volume measure, we have been frustrated. Archimedes law.
You need to have the volume and the mass to calculate the density
The volumes of all objects are expressed in the third power of whatever units are being used to measure their dimensions. For example, if an object is very small and you measure its dimensions in millimeters, its volume would be expressed in cubic millimeters.
You can measure the volume of irregular solids by using water displacment which is meausured in mililiters (mL), and that, in turn, can be converted to cubic centimeters (cm3)
it can be found by first taking the volume of the water itself and then the volume of the object in the water. you pour water into the 12-sided object, then measure the amount of water using the graduated cylinder. Then you do this: length x width x height = volume
To do this, you will need to measure the length and the width and the height and your have your answer to the volume.
Used to measure irregular objects volume.
To measure volume of large irregular shaped objects you need a displacement can
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.
Volume of irregular or regular shape object is the space reserved by the object in any medium.
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.
Volume of irregular or regular shape object is the space reserved by the object in any medium.
Yes. Obviously it doesn't work for all objects.
Archimedes
If the object is irregular the best way is to measure the volume of water it displaces when you immerse it completely in water.
A graduated cylinder is used for measuring the Volume of different things such as irregular objects. It uses the unit ml. It has a miniskus FYI that is when you use water and if you look closely you can see it curve at the top. You measure the miniskus a the bottom of the Curve. Also to find the Volume of an irregular object you first measure the water (starting volume) then place the Object in it and you will have your ending volume. then subtrct the difference from the starting volume and the ending and you will have your volume in ml.
