On Children's Day, my mother gave Min Min a big cake. The cake box is cylindrical, and the waiter aunt said it would be beautiful with a cross-shaped ribbon, you know.
It is known that the cake is cylindrical, with a diameter of 50cm and a height of 15cm.
Make a cross, that is, make a circle from two directions of the cake, and make a circle across two diameters+two heights of the cake.
Two turns around is (50*2+ 10*2)*2=240cm, and tied with a 25cm ribbon, which is 275cm long.
