How many 1-gallon cans will fit in a 55-gallon drum?

To determine how many 1-gallon cans will fit in a 55-gallon drum, you need to divide the total volume of the drum by the volume of each can. Since there are 128 fluid ounces in a gallon, a 1-gallon can is equivalent to 128 fluid ounces. Therefore, a 55-gallon drum is equal to 55 x 128 = 7040 fluid ounces. If we divide 7040 by 128, we find that approximately 55 1-gallon cans can fit in a 55-gallon drum.
