So that the irregular solid isn't wet when you place it on the balance, since that would make it appear to have a greater mass than it actually does.
No. Density is an intrinsic property and does not depend on the amount or size of the sample. If you are referring to finding the volume of an irregular solid by water displacement, then you will get a very large experimental error if the solid sticks out of the water. The amount of water added to the graduated cylinder initially, must be enough to completely cover the solid, before you place the solid in the cylinder.
The pieces are then dipped in a cup full of liquid volume measure, we have been frustrated. Archimedes law.
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)
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 volume of a solid you can't simply calculate, get a large tub of water in which you can completely immerse the solid. Fill the tub with water to the edge, then submerge the solid. Any water that spills over has been replaced by the solid and signifies the amount of space the solid is now taking up. Weigh the water or put it in 1l bottles. 1kg of water is 1l and a liter is a cubic decimeter. From there you can calculate the volume in any unit you want.
Irregular solid volume is still measured in cm3 etcTo Find the Volume of an irregular object you can,Measure out a proportional amount of water to the object you are finding the volume ofPut the object in the container of waterSee how much the water has risen byYou now have the volume!!(The difference between the new and old volumes of water is the volume
There is no formula for finding the volume of an irregular solid. One method is water displacement which works as follows: Fill a graduated container with water and read off the volume of water. Then you submerge the irregular shaped solid in the water and measure the volume inside the container again. The difference between the two levels is the volume of the solid. This clearly cannot work for solids that are soluble in water. Other fluids may have to be used in such cases. Also, it will not work if the solid floats on water, but in that case you can submerge it using additional weights (whose volume you have measured).
graduated cylindergraduated cylinderSubmerge your solid in a liquid the liquid volume displaced is equal to your irregular solid volume.
The water displacement method is typically used to find the volume of an irregular solid. The object is submerged in a known amount of water, and the increase in water volume is measured. This increase in volume is equal to the volume of the irregular solid.
It's simple, you just have to take a measurable recipient big enough to contain the solid, fill the recipient with a known volume of water and drop the irregular solid into the water. Then you can measure the increase of volume, which will be equivalent to the volume of your solid.
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.
Eureka!There really isn't a "formula" for discovering the volume of an irregularly shaped solid. Instead, submerge the irregular solid in water and measure the volume of water it displaces to discover its volume. The ExperimentFor finding the volume of an irregular solid we just fully dip (submerge) it in a water tank which is fully filled with water and is attached to an another tank (a cylindrical overflow tank) through a pipe. With the setup in place, we put the solid into the full tank. The solid will displace water, which will flow through the pipe into the overflow tank. Further, the volume of the water the solid displaces will be equal to the volume of that irregular solid. Now we calculate the volume of water in the overflow tank using the depth of that water and the diameter of the tank. The volume of the displaced water will equal the volume of the irregularly shaped solid.There will generally not be a formula and the volume will have to be measured in some other way.

You are finding the volume of the solid figure.To find the volume of a solid figure, depending on the size of the object, you can use a graduated cylinder. You can fill the cylinder up to x amount of water and then measure the amount after dropping the solid into the water, and then subtract the amount before, from the amount after, to get the volume of a solid. You can also use simple mathematics to figure the volume of the solid. There are different formulas for calculating volume for different types of solid figures.
The method used to measure an irregular solid by placing it in water is called dispersion. If you note the level of the water before placing the object in and the level after, you can find the volume of the object by calculating the difference.
yes you can use a balance to measure the volume of an irregular shaped solid.
