To calculate the number of pennies needed to fill a 7-gallon jug, we need to consider the volume of a penny. A penny has a volume of approximately 0.36 cubic centimeters. One gallon is equivalent to approximately 3785 cubic centimeters. Therefore, a 7-gallon jug would have a volume of 26,495 cubic centimeters. Dividing the volume of the jug by the volume of a penny gives us approximately 73,597 pennies needed to fill a 7-gallon jug.

The answer will depend on whether you mean UK pennies and the Imperial gallon or US pennies (which are actually cents) and a measure that is a smaller gallon, or a penny from some other country and yet another arbitrary measure which is called a gallon!
