\n" );
document.write( " lateral surface Area (4 sides) = 2lh + 2wh    ||Note square prism, l = w = h = x
\n" );
document.write( "     2x^2 + 2x^2 = 324
\n" );
document.write( "           4x^2 = 324
\n" );
document.write( "            x^2 = 81
\n" );
document.write( "             x = 9   (throwing out negative solution for length of a side) \n" );
