\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "    1.  The bottom area of the open box = \"Volume%2FHeight\" = \"1536%2F6\" = 256 cm^2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    2.  The side measure of the box bottom = \"sqrt%28256%29\" = 16 cm.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    3.  The side dimension of the original square piece of tin is 16 + 2*6 = 28 cm.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    4.  The area of the original piece of tin is 28^2 = 784 cm^2.\r\n" );
