Use the Archimedes' method, fill a container with water (right to the top) with a spill tray underneath to catch the water over flow, drop the rock in and measure the amount of water displaced. This method will be about as accurate as you can get.
Place the rock in water in a graduated cylinder, but first make a note of the volume of water in the cylinder before you place the rock, and then again after you place the rock. The difference in the two readings is the volume of the rock, since a submerged item will displace exactly its volume of fluid.
You use displacement.
STEPS
-fill a graduated cylinder with a certain amount of water(make sure to record the volume of the water in mL)
-then place the rock inside the graduated cylinder and measure the new volume or after result
-subtract the volume of water by itself from the volume of water with the rock
-convert your result of mL to cm cubed 1 mL= 1 cm cubed
Place the rock in a container of water. The difference in weight and volume caused by introducing the rock is its actual weight and volume, provided it's not lavastone which has enough air bubbles to cause it to float.
If the object is insoluble in water then we can use immersion technique and measuring the expelled water by a measuring jar.
Immerse it in water and the volume of water displaced is equal to the volume of the object.
Immerse it into water and the water displaced is equal to the volume of the object.
The answer depends on the material of the object. Fluid displacement will only work if the object is not soluble in the fluid.
subtract mass and weiht
Personally, what I would do would be to experimentally find a lead fishing sinker, rock, gold coin etc., which, when added to the irregular object, sinks them both. For accuracy, the object selected should be smaller than the irregular object. The smaller, the better. Then, in the usual way, find the volume of the sinker, the rock, or the gold coin alone. Write it down so I don't forget it. Finally, glue the 'ballast' to the irregular object, and measure the volume of the combination by sinking it. From the volume I find, subtract the volume of the ballast alone, and I'll have the volume of the irregular object.
Weight it. Find it's volume. (hint - how much water does it displace). Divide.
Not always easy. Since density is defined as the mass of a unit volume of material,you would measure the volume of the rock by putting it into a container half filled with water and then measure the volume change.
To find the volume of an irregular object you may use water displacement. This is basically measuring an amount of water in a graduated cylinder, adding the object, and seeing how much the water level rises. Since 1mL=1cm3, the difference in the two water levels is the volume of the object in cubic centimeters.
There are a number of tools that are needed to find the density of a rock. You will mainly need a scale to measure the weight and the volume of the rock. Divide the mass of the rock by the volume to find the density.
He discovered the method to calculate the volume of a irregular object (rock).
To find the volume of an irregular object such as a rock, you have to use displacement. If you place the object in a graduated cylinder filled with water, the volume of the object is equal to the amount of water that the object displaces. For example, if a graduated cylinder is filled with 100mL of water, and you place an object such as a rock and the water rises from 100mL to 106mL, then the volume of the rock is 6.
[object Object]
The volume of a solid object such as a rock or pebble can be determined by submerging it in a liquid in a graduated cylinder or other container. The difference in the volume of the liquid is the volume of the object.

For accuracy, the object selected should be smaller than the irregular object. The smaller, the better. Then, in the usual way, find the volume of the sinker, the rock, or the gold coin alone.

You would measure the length width and heighth. Then you would multiply them all together. <><><> A better means would be to have a container that the rock will fit in, and fill it full of water. Place the rock in the container, which will overflow. Then remove the rock, and measure the volume of water you have to pour into the container to make it full again. The volume of the water will equal the volume that was displaced by the rock.
The best way to find the volume of an irregular solid is to submerge it in a liquid and see how much the liquid rises. You can also use calculus and tripple integrals, but that gets really sticky.
no
Because most rocks are not made up of common geometric shapes, it would be difficult or impossible to find the volume of a rock using a ruler; there would be no easy way to measure the rock's irregular volume. However, by measuring the volume of liquid a rock displaces, its volume can easily be determined.
A regular object is an object that can be measured easily. Like a cube of wood, or a rectangular eraser. An irregular object is an object that can not be measured easily. Like a lump of clay or a rock because it has no exact measurements.
no
Any regular shape,like a cube or sphere, can be described mathematically and its volume can be calculated easily. An irregular shape, such as a rock can be mesured by displacment of water, or by scanning it in three dimensions.If the object's density is known, it need only be weighed. volume is a amount of mater space takes up TY!
