![]() The volume by a water displacement method. He weighs the idol and measuresthe idol and returning with it to his He decides to determine if it is really pure gold. Let’s assume that Indiana is successful in removing laboratory. Assuming the idol is pure gold, what volume would thto weigh exactly the same as the idol and not set off the booby-traps?e bag of sand have to be in orderī. Of gold is 19 g/mL and the density of sand is 2 g/mL.ġ. To prevent this from happening, Indiana nsity The volume of the gold idol is approximately 1 L. The deidents.
