<Look at the figure for lbs again it's a double cube 'it amounts to an Av/Lb. total of 62.25 Lbs' / 2 = 31.125 and cube root = 3.14559.
Pi cubed = 31.00627 x 2 = 62.0125>
Careful with those calculations, they might get you into Hot Water as the graphs indicate in the Engineer's Toolbox will attest.
I miscalculated the density of a cubic Ft. of water and just now corrected the value to 62.5 Lbs. Let's see, your calculation would give a density of Water at around 96*F, according to this chart's increments. Nice temp. for hot tubing this time of year anyhow. :) Just thought I would add to this post now that the figure of 1/2 62.5 at. 31.25 cube rt. = 3.149802625, still makes for an interesting Pi value very near to that of 3.15 value that Jacob uses quite often in his Polar Radius calculations derived from J.Michell's Canonical Model.
