Find a fluid in which the object is insoluble and measure the amount of fluid displaced when the object is completely immersed. This may present a challenge if the density of the object is less than the density of the fluid but you can design an experiment to do this. In doing so, you will be recreating the idea that we ascribe to Archimedes. It is told that when he was in his bath and realized that an object submerged would displace a volume of water equal to its own volume, he leapt from the tub, and, in his excitement, ran naked through the streets shouting, "Eureka!" Well, that was the word on the street at the time....
We first measure its mass m/g using a balance.
Then, we find its volume V/cm3 the displacement method. This is done by finding the volume of water it displaces when it is placed in a measuring cylinder of water.
Its density d is given by: d= m/V gcm-3
you totally sink it into a fluid, "the volume by which the level has risen" is the volume of the object. Capito?
You divide the irregular shape into a buch of smaller regular shapes. Find the volume for those, add them up...and you have the volumee.(:
The volume of an irregularly shaped solid can be measured by placing the solid in a known quantity of water in a container with measurement markings. Take the new volume and find the difference between this and the old volume. This is the volume of your irregularly shaped solid.
When you are trying to find the volume of an irregularly shaped object.
Use volume displacement method.
break it up into pieces you know how to find the volume of
Take an amount of water of which you know the volume. Drop the object in the water. Find the difference
It is used to find the volume of an irregularly shaped object. An object dropped into a volume of water will displace an equal volume of water.
The volume of an irregularly shaped solid such as a watch is found by immersing that solid in water inside a graduated cylinder. You can then simply read the change in water level off the markings on the cylinder. Of course, if your watch is not water proof, this may not be such a good idea.
Get a sample of the metal. Use a scale to find its mass. If it is shape is that of a rectangular solid (box) measure length, width, and height and multiply to find volume. If it is irregularly shaped, use the water displacement method to find its volume. Divide the mass by the volume to get the density.
mass over volume
It is the displacement method.
To find the volume of a rectangular prism, multiply the base, width, and height. If the prism is irregularly shaped, multiply the base and the height.
Weight it. Find it's volume. (hint - how much water does it displace). Divide.
