You can put this solution on YOUR website!
d^2 = L^2 + W^2 + H^2 = 11^2 = 121
\n" ); document.write( "L^2 + W^2 + H^2 = 121
\n" ); document.write( "L + W + H = 19
\n" ); document.write( "---------
\n" ); document.write( "--> 6 by 6 by 7
\n" ); document.write( "SA = 2LW + 2LH + 2WH
\n" ); document.write( "SA = 72 + 84 + 84 = 240 sq cm
\n" ); document.write( "Other solutions are possible.
\n" ); document.write( "-----
\n" ); document.write( "After thinking about it, that's the only solution.
