Since we don't know the weight of the cube itself, we can only tell the weight of the water. Since the volume of a 3-foot cube is 27 cubic feet, we find that 27 cubic feet is equal to 202 gallons. Because one gallon of water weighs about 8.35 pounds, we multiply 202 x 8.35 for a result of 1,686.7 pounds for the water alone.
