this is a 3 dimensional pythagorean theorem and is expressed as
\n" ); document.write( " $\"d+=+sqrt%28l%5E2+%2B+w%5E2+%2B+h%5E2%29\"$
\n" ); document.write( "or
\n" ); document.write( " $\"d+=+sqrt%285%5E2+%2B+4%5E2+%2B+3%5E2%29\"$
\n" ); document.write( "which is
\n" ); document.write( " $\"d+=+sqrt%2825%2B+16+%2B+9%29\"$
\n" ); document.write( "or
\n" ); document.write( " $\"d+=+sqrt%2850%29\"$
\n" ); document.write( "so,
\n" ); document.write( " d = 5sqrt(2) \n" ); document.write( "
