\n" ); document.write( "To cover the 6' width he will need 12 boards that are each 6 \" wide.
\n" ); document.write( "When he cuts the 8 ft long board to get a 6' length he has a 2' piece
\n" ); document.write( "left over. But he cannot use that scap piece because it is less than
\n" ); document.write( "3 feet long.
