In theory, a 5-gallon jug filled completely with $100 bills can contain a total of $980,000. If the jug is filled with $1 coins, it could hold a total of $33,333. The amount varies widely depending on the combination of coins and bills used to fill the jug.
Based on measurements, a stack of 100 $100 bills is 6 inches long by 2.5 inches wide by 0.43 inches tall, giving the stack a volume of 11.785 cubic centimeters. A 5-gallon jug contains the equivalent of 1,155 cubic inches. Dividing 1,155 cubic inches by 11.785 cubic inches per stack of bills gives a total of 98 stacks of $10,000. Multiplying 98 stacks by $10,000 gives a total of $980,000. The same process can be used to find the volume of $1 coins contained in a 5-gallon space.
