12*3*x=36x ft^3 is the volume to be filled.
\n" ); document.write( "36x=70*.13368
\n" ); document.write( "36x=9.3576
\n" ); document.write( "x=9.3576/36
\n" ); document.write( "x=.2599 ft. is the depth of the 70 gallons of water.
\n" ); document.write( "Proof:
\n" ); document.write( "12*3*.2599=70*.13368
\n" ); document.write( "9.3564=9.3576
