The volume to be filled is \"+15%2A18%2A%281%2F2%29+=+135+\" ft3
\n" ); document.write( "A cubic yard is \"+3%2A3%2A3+=+27+\" ft3
\n" ); document.write( "\"+135+\" ft3 x \"+1+%2F+27+\" yd3 / ft3 = \"+5+\" yd3
\n" ); document.write( "3 sacks = 1 yd3
\n" ); document.write( "\"+5+\" yd3 x \"+3+\" sacks / yd3 = \"+15+\" sacks
\n" ); document.write( "\"+6.8+\" dollars/sack x \"+15+\" sacks = \"+102+\"
\n" ); document.write( "The cement will cost $102
