A cube has 4 equal sides.
\n" ); document.write( "Let x to be one side of the cube.
\n" ); document.write( "Since a cube has 4 equal sides, so $\"4x=20cm\"$ .
\n" ); document.write( " $\"4x=20cm\"$
\n" ); document.write( " $\"x=20%2F4\"$
\n" ); document.write( " $\"x=5cm\"$ \r
\n" ); document.write( "\n" ); document.write( "Area of cube = length x width
\n" ); document.write( "Area of cube = 5 x 5
\n" ); document.write( "Area of cube = $\"25+cm%5E2\"$ \n" ); document.write( "

\n" );
