the slab :
\n" ); document.write( "\"W=15ft\", \"L=10ft%7D%7D%2C+and+%7B%7B%7Bh=6in\" \r
\n" ); document.write( "\n" ); document.write( "Concrete is usually sold by the \"cubic\" \"+yard\".\r
\n" ); document.write( "\n" ); document.write( "first convert everything in \"+yards\"\r
\n" ); document.write( "\n" ); document.write( "\"1Foot+=+0.333Yards\"
\n" ); document.write( "\"1Inch+=+0.02778Yards+\"\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "\"W=15ft\"=> \"W=15%2A0.333Yd\"=> \"W=+4.999Yd+\"
