-----------------
We all LOVE English units, they're so convenient.
------------
In inches, it's
48 x 15 x 36
= 25,920 cubic inches
cu ft = cu in/1728 (1728 = 12 x 12 x 12)
= 15 cubic feet
Water weighs 62.4 lbs/cf,
so 15 x 62.4 = 936 pounds
--------
A gallon is 231 cu inches.
25920/231 = 112.2 gallons
