In Reply to: How many gallons in a rectangular tank 71"X8"X16" ? posted by wrecklessdiver on April 24, 2002 at 00:33:23:
I always convert to feet first....
71/12 = 5.91
8/12 = 0.67
16/12 = 1.33
Approximation formula is 7.5 * (w x h x l), where the dimensions are in feet, thus:
7.5 X (5.91 X 0.67 X 1.33) = 39.5 (approx) gallons.
