Respuesta :
One way to measure the volume of an irregular object (a rock in your case) is to completely submerge it in water and measure the change in height of the water level. This change in water level (let's say from 50ml to 65ml) indicates that the volume of the stone is 15ml.
What are the ways to measure the volume of the water plus the rock ?
The volume of the stone depends on the size of the stone. Since rocks are irregularly shaped bodies, their volume is easily determined by the displacement of water. When an object is placed in water, the amount of water displaced by the object is equal to the volume of the object. Density is an important property of rocks as it helps identify the type of rock and its geological structure.
To calculate the density of a rock, we need to divide the rock's mass by its volume. The latter can be determined by placing the rock in a graduated cylinder filled with water.
Calculation ;
Add 30ml of water to the graduated cylinder. 30 ml is the starting water volume. Carefully put the stone into the water. You will see the water level in the graduated cylinder rise. Suppose that the water level rises to 50 ml when a stone is added. 50 ml is the final volume of water.
To find the volume of the stone, subtract the initial water volume from the final water volume: 50ml - 30ml = 20ml. So the volume of the rock will be 20 ml or 20 cm³.
