Solution:Let x the measurement of cube, The surface area A of cube is \r
\n" ); document.write( "\n" ); document.write( "\"A=6x%5E2\", where\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2\",is the area of one side, and the cube has 6 equal sides.\r
\n" ); document.write( "\n" ); document.write( "\"864=6x%5E2\", divide both sides by 6\r
\n" ); document.write( "\n" ); document.write( "\"144=x%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"x=sqrt%28144%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x=12\"\r
\n" ); document.write( "\n" ); document.write( "Answer: the measurement of the cube is 12 ft.
