\n" ); document.write( "8 x 9 x 11
\n" ); document.write( "There are 2 facing wall measuring 8 x 11
\n" ); document.write( "There are 2 facing walls measuring 8 x 9
\n" ); document.write( "Let \"+A+\" = the combined area of the 4 walls
\n" ); document.write( "\"+A+=+2%2A8%2A11+%2B+2%2A8%2A9+\"
\n" ); document.write( "\"+A+=+2%2A8%2A%28+11+%2B+9+%29+\"
\n" ); document.write( "\"+A+=+16%2A20+\"
\n" ); document.write( "\"+A+=+320+\" ft2
