Original volume of cube with side = xcm:
\n" ); document.write( "\"V%5B1%5D+=+x%5E3\"cc.
\n" ); document.write( "New volume of cube with side = 2x:
\n" ); document.write( "\"V%5B2%5D+=+%282x%29%5E3\" and V = 64,000cc.
\n" ); document.write( "\"64000+=+8x%5E3\"
\n" ); document.write( "\"x%5E3+=+8000\" so...
\n" ); document.write( "\"x+=+20\"cm.
\n" ); document.write( "Area of one face of original cube is:
\n" ); document.write( "\"A+=+x%5E2\" x = 20
\n" ); document.write( "\"A+=+400\"sq.cm.
\n" ); document.write( "
\n" );
