Irregularly shaped objects have no formula for finding the volume. So, to find the volume of a rock, one method is to measure how much water the rock displaces. You simply need some sort of container that measures the volume of liquids and you need some water. The container should be large enough to put the rock in. First, fill the container to a certain volume, noting what that volume is and making sure that enough water is used to completely cover the rock when you put the rock in the container. Next place the rock into the container and measure the new volume indicated by the water. Subtract this new volume with the old volume, and the answer will be the volume of the rock. Another method is to use the rock's mass and density to calculate the volume. This can be tougher because you might not know what type of rock you have and many rocks are composites of different types of rocks. Some internet websites give the densities of different rocks. The website http://www.earthsci.unimelb.edu.au/ES304/MODULES/GRAV/NOTES/densities.html gives some simple densities. But if you have all this information, the volume can be determined by measuring the mass of the rock and dividing that number by the density.

How do you find out the volume of a rock?

Height times width times length equals the volume of the rock.


How would you find the volume of an irregularly shaped object such as rock?

You can find the volume of an irregularly shaped object, like a rock, by using the water displacement method. Submerge the object in a known volume of water in a container. Measure the increase in water level, which equals the volume of the rock.


How would you use your calibrated bottle to find the volume of the rock?

Place a specific amount of water in your bottle. Record the volume. Place the rock in the bottle. Read and record the new volume of water. Subtract the first volume measurement from the measurement after you added the rock. The difference is the volume of the rock.


How do you find the volume of an odd size rock?

The volume of an odd size rock can be obtained through methods like displacement method.


How would you find the density of an irregularly shaped object such as a rock?

To find the density of an irregularly shaped object like a rock, you can use the water displacement method. First, measure the volume of water displaced when the rock is submerged in a known volume of water. Then, divide the mass of the rock by the volume of water displaced to calculate the density.


How do you find mass of a rock by its density?

Determine its volume by how much water it displaces, then divide mass by volume


How can you find the density of a rock or key?

Find the mass using a scale. Find the volume by the water displacement method. Divide mass by volume and that equals density.


How can you find the volume of a rock that is too big to fit into a graduated cylinder?

One way to find the volume of a large rock is to use the water displacement method. Fill a container with a known volume of water, then carefully lower the rock into the water. Measure the change in water level to determine the volume of the rock.


How do you find density of a rock?

The simplest way is to use the formula: P = m / V Density = mass / volume So to calculate the denisty of the rock you will have to find out how much it weighs and how much volume it occupies. You can measure the weight by placing the rock on a weighing scale, this will give the weight in grams. You can determine the volume by submerging the rock in a measuring cup partially filled with water and measuring how much the volume increases. This will give the volume in cm3 Now use the formula to calculate its density in g/cm3.


Describe a method that the student could use to find the volume of this rock?

You can find the volume of a small rock in no time at all. Just fill up a container that is marked by volume with water and record the volume. Then drop the small rock inside the container. Record the new volume. Find the difference between the new and old volumes. This is the volume of the small rock. You could do this in any liquid.


Can a rocks volume be 250 mL?

Yes. It would be hard to find a rock with that volume, but I'm sure there is one out there.


A rock has a density of 4 gml and a mass of 16 grams what is the volume this rock occupies?

To find the volume of the rock, you can use the formula: Volume = Mass / Density. Plug in the values: Volume = 16 grams / 4 g/ml = 4 ml. So, the rock occupies a volume of 4 ml.
