How does finding the volume of the water that was displaced help you find the volume of the mineral itself?

Finding the volume of water displaced by a mineral allows you to determine the mineral's volume based on Archimedes' principle. When the mineral is submerged in water, the volume of water displaced is equal to the volume of the mineral itself. By measuring the displaced water accurately, you can calculate the mineral’s volume without directly measuring its dimensions, which is particularly useful for irregularly shaped objects. This method provides a straightforward way to assess the mineral's volume in a practical setting.
