Indiana Jones Density Problem
Name_____________________________
Period__________
In the 1981 movie “Raiders of the Lost Ark”, there is a scene where Indiana Jones attempts to switch
a gold statue with a bag of sand. The gold statue is protected from theft by a triggering device. The
switch must be made with a mass that is equal to the gold statue to avoid springing the trap and
bringing disaster to Indiana Jones.
Mass Versus Volume
The density of sand is 2.5 g/cm 3 and the density of gold is 19.3 g/cm 3. The approximate volume of the gold
statue is that of a large pickle bottle or 1.0-quart. One quart is equal to 0.946 liter and 1 liter is defined as 1
dm3. Another useful conversion is 1 pound equals 453.5 grams.
Did Indiana Jones have a reasonable chance of exchanging the bag of sand for the gold statue? Determine
the mass of the bag of sand and the mass of the gold statue in grams, if they both had a volume of 1 quart.
Determine the volume of sand needed to give the same mass as the gold statue.
If the gold statue was hollow or made of brass, density = 7.8 g/cm 3, would there be a reasonable chance for
a switch?
