To calculate the surface are of a cube, find the surface area of one side and multiply by 6. The surface area of any side is the length of a side squared.

\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.
