A nugget of gold is placed in a graduated cylinder that contains 85 mL of water. the water level rises to 225 mL after the nugget is added to the cylinder. what is the volume of the gold nugget?

To get the volume of an object, one of the oldest techniques is to fill a container with water of which we know the volume (in this case 85mL), and drop the object in. The water will rise and show a new volume (225mL). If we subtract the old volume (85) from the new volume (225), we will get the volume of the object (225 - 85 = 140).
