The surface area of any side is the length of a side squared. \n" ); document.write( " \n" ); document.write( "So: SA = 2(length*width) + 2(height*width) + 2(length*height)\r \n" ); document.write( "\n" ); document.write( "2(12*12)+2(12*12)+2(12*12)\r \n" ); document.write( "\n" ); document.write( "2(144)+2(144)+2(144)\r \n" ); document.write( "\n" ); document.write( "288+288+288 = 864 inches.\r \n" ); document.write( "\n" ); document.write( "So the answer is: 864 inches. \n" ); document.write( " |
