What do you use to find the volume of an irregular solid?

Answer 1

You put water in a bowl and measure how much water you have in the bowl. Then place the object in the bowl and see how much water you have now. Then subtract what you have now by the measurement you had before and that's the volume of the irregular object.

Answer 2

Fill an appropriately sized container with Water to the very brim. Now slowly and carefully lower the object into the water. The container needs to sit in a deep bowl which is large enough to catch ALL the overflow. Now remove the container, with the object still in it, from the deep bowl. The water which overflowed into the bowl will have EXACTLY the same VOLUME as the object you placed in the water. Carefully pour ALL the water in the BOWL, into a graduated measuring container such as cooks use in the kitchen. Your answer will be the amount of water in your measuring container. Kitchen measure containers are not very precise, but they are reasonably accurate for the purposes of learning. DO NOT assume that, that gives you an answer to the Weight of the object. Weight and Volume are 2 distinctly different things we can measure. Many question on this website indicate to me that many people do not understand the concepts of 'weight' & 'volume' and the differences between them.

Answer 3

When you want to measure the volume of irregular solids place it in a container containing water.The solid if it sinks in water will displace the water to occupy space.The difference in the actual measure of water and the displaced water is the volume of the solid.

(this is called Archimedes' Principle)

Answer 4

water displacement method
Divide the object into regular shapes calculate volume seperately, then add together.

METHOD USE IN VOLUME

• line
• time
• density
• weight
• fine
  
• early
• gone
  
• inertia

To find the volume of an irregular solid, you can use the water displacement method. You take a certain volume of liquid that is measured to a line (like in a measuring cup) so you know it's exact, and drop the solid in the water and see how much it rises. The difference between the water with the solid and the water without is the volume of the solid.
It's not easy to find exactly.

The best way is to drop the object in a fluid (i.e. water) then see the volume of the fluid that is displaced.

In a lab, you could use a volumetric flask for small objects.

For example, if you had 100 cm3 of water in the flask, you put the object in, then you found that the new volume of water was 122 cm3, you would know that the object's volume was 122-100 = 22 cm3.

Answer 5

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.

Answer 6

In general terms, by using the Archimedean principle. If the solid is immersed in a liquid, it will displace a volume of that liquid which is equal to its own volume. The volume of liquid displaced is then measured.

Answer 7

Water displacement

Answer 8

You take the solid and put it in a graduated cylinder mostly filled with water. Then pop in the solid. the difference in numbers is the solid's volume

Answer 9

height and width
