Not all 55 gallon drums are the same size in height and diameter. To get an accurate check measure the diameter in inches and divide by .5 (this is the radius). Square that number - multiply by pi (3.14) and divide by 231. This will give you the gallons per inch. Good Luck Bob Raymond Bob.Raymond@kelleytech.com
4 ft. 7 is 55 inches, one inch less than 56
55 + 55 = 110 55 - 55 = 0 55 / 55 = 1 55 * 55 = 3025
