Fill a graduated cylinder with water.
Record the amount. Let's say this amount is X.
Drop the rock in.
Record the new amount. This amount is Y.
Now subract X from Y.
So it should look like this:
Y-X=Z
Z is your answer.
This is called the Water Displacement Method.

Is multiplying the length x width x height a good method to find the volume of a rock?
No. I say this because a rock is usually circular and not a perfect figure. :-)
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.
How do I find the volume of a rock?
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 is the mass of a rock measured?
You put it on a scale or a triple-beam balance. It'll give you the mass. However, if you have the density of the rock, divide it by the volume to find the mass mathematically. You can also find the volume by the water displacement method, where you placed the rock in a graduated cylinder/beaker filled partially with water and record the difference between the original water level and the raised water level after placing the rock inside the container.
How can the volume of a irregularly shaped rock be measured?
One way would be to get a container into which you could put the rock completely, fill it to the brim with water (without the rock in it), then put the rock in and measure the volume of the water that flowed out.
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 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.
What did Archimedes find?
He discovered the method to calculate the volume of a irregular object (rock).
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 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 would you determined the volume of the rock?
For complex shapes finding the volume is quite difficult. You could do it one of three ways: Simplify the rock's shape, say as a sphere, then use 4/3(pi)(radius^3) to find the volume. Or you could integrate the surface area. I suggest you look up how to do this, since it cannot be easy taught. If you are looking for a simple answer, stick with the first method. Another method is, if you know the density of the rock you can weigh it and find the volume using: mass/density = volume
Describe a method that the student could use to find the volume of this rock?
The student can find the volume of the rock by using the water displacement method. First, fill a container with water and note the water level. Then, submerge the rock in the water and measure the new water level. The difference in water levels gives the volume of the rock.
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.
Is multiplying the length x width x height a good method to find the volume of a rock?
No. I say this because a rock is usually circular and not a perfect figure. :-)
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.
Why is the graduated cylinder used instead of a ruler to measure the volume of a rock?
A graduated cylinder is used to measure the volume of irregularly shaped objects like rocks because it can provide a more accurate measurement by allowing the water level to rise precisely to the volume of the object when submerged. This method takes into account the irregular shape of the rock, unlike measuring with a ruler which would only provide an approximation of volume based on dimensions.
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.
