First, two things. 1) Since brass is a solid at standard temperature and pressure, it is unusual to specify its density in fluid volume units, such as gallons. 2) Brass is an alloy comprising differing amounts of different metals, so its density must be specified as a range. Brass is about 8.5 times denser than water. It has a density of 8.4 to 8.75 grams per cubic centimeter. That translates to 70 to 73 pounds per US gallon.

Brass weighs approximately 530 pounds per cubic foot, which is equivalent to 0.06715 pounds per cubic inch. So, based on the density of brass, a gallon of brass would weigh around 16.5 pounds.
Mass = volume x density
You need the density of the type of brass involved.
The volume of a cube is l3.
Ice weighs about 8.34 pounds per gallon, so 21 gallons of ice would weigh approximately 175 pounds.
A gallon of 30-weight motor oil weighs approximately 7 pounds.
