CONVERTING ALL MEASUREMENTS TO INCHES WE HAVE:
\n" ); document.write( "1-9=21
\n" ); document.write( "2-3=27
\n" ); document.write( "3-6=42
\n" ); document.write( "NOW WE'LL NEED 2 PIECES OF ALL COMBINATIONS OF SIDES THUS
\n" ); document.write( "2(21*27)+2(21*42)+2(27*42)
\n" ); document.write( "2*567+2*882+2*1134
\n" ); document.write( "1134+1764+2268
\n" ); document.write( "5166 SQUARE INCHES.
\n" ); document.write( "DIVIDING THIS FIGURE BY 144 (NUMBER OF SQUARE INCHES IN A SQUARE FOOT) WE GET:
\n" ); document.write( "5166/144=35.875 SQUARE FEET OF WOOD.
\n" ); document.write( "IF YOU WOULD RATHER WORK IN DECIMALS THEN:
\n" ); document.write( "1-9=1.75
\n" ); document.write( "2-3=2.25
\n" ); document.write( "3-6=3.5
\n" ); document.write( "2(1.75*2.25)+2(1.75*3.5)+2(2.25*3.5) ETC.
\n" ); document.write( "
