You fill the granulated cylinder with some water and note how much there is in there.
Then you put in the rock and see what the new water level is.
You subtract the new water level with the old one and that's your answer.
You use a graduated cylinder to measure the volume of the rock with the water and the water without the rock
Step 1 . calculate the volume of the cylinder step 2 . put the rock in the cylinder and fill it with water to the top step 3. measure the amount of water step 4 subtract the volume of the water from the volume of the cylinder, and you have the volume of the rock.
Fill the cylinder about half way with water and measure the amount. Then drop the rock in and measure the amount of water. Now subtract no rock from rock in and that will give you the amount of volume displaced from the rock.
Fill the cylinder with water to a marked point. Then place the rock in the water and measure how much the water level rises. That will give you the amount of volume displaced by the rock and so the volume of the rock.
To measure a rock using a measuring cylinder, you can follow these steps: Fill the measuring cylinder with water up to a marked level. Note down the initial water level. Carefully place the rock into the water, ensuring it is fully submerged. Measure the new water level and calculate the difference to determine the volume of the rock.
Fill a beaker or measuring cylinder with water and record the volume of water indicated. Put the rock in the beaker/measuring cylinder and record the new volume of water indicated. The difference between the two volumes is the volume of the rock.
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.
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.
Divide each rock's mass by its volume. The rock with the higher number is denser. To find the volume, measure the rocks in a graduated cylinder, the one that displaces more water is denser.
To determine the density of an irregular rock, you can use the water displacement method. First, measure the initial volume of water in a graduated cylinder. Then, submerge the rock completely in the water and measure the new water level; the difference in volume indicates the rock's volume. Finally, divide the mass of the rock (measured using a scale) by the volume obtained from the water displacement to calculate the density.
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.
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.
