**DrBob222**, Tuesday, February 17, 2009 at 12:47pmThere is a law is physics called the law of impenetrability. In its simplest terms, it says that two objects can't occupy the same space at the same time. In reference to the orange juice and marble, both juice and marble can't occupy the same space at the same time. So if the OJ occupied 75 mL without the marble and it occupied 90 mL with the marble, it should be obvious that the marble took up 15 mL of space so that is the volume of the marble. You will want to draw a diagram showing the glass, the OJ at 75 mL, the marble separately, the volume of OJ AND marble, etc. You can make a very interesting series of drawings to show what you want to show. Good luck.
