\n" ); document.write( "-----------------
\n" ); document.write( "There are (2) 7 x 4 surfaces
\n" ); document.write( "There are (2) 7 x 5 surfaces
\n" ); document.write( "There are (2) 4 x 5 surfaces
\n" ); document.write( "That is \"+3%2A2+=+6+\" surfaces total
\n" ); document.write( "\"+2%2A%28+7%2A4+%2B+7%2A5+%2B+4%2A5+%29+=+2%2A%28+28+%2B+35+%2B+20+%29+\"
\n" ); document.write( "\"+2%2A83+=+166+\" square units
