Question from LaDonna:

My container is 50" across and 40.5' ft. long. I believe it would hold 140 barrels. If measuring, how many barrels would this container hold per inch?


I am going to assume, based on your email address, that your barrels are units of volume used in the petroleum industry. Barrels in the wine and beer industry for example are not the same size. I looked in and found that a barrel in the petroleum industry is 42 US gallons or 9702 cubic inches. Your container is 50 inches wide and
40.5 x 12 = 486 inches long. Thus one inch of depth in this container is

50 x 486 x 1 = 24300 cubic inches

which is

24300 / 9702 = 2.5 barrels.
