Drag the amounts to order them from greatest to least.
1 in. ≈ 2.54 cm 1 ft = 12 in.

1.8ft 56cm 20in

So the first thing to do is get all amounts into one common unit. I will convert them all to ft.

1.8ft.
20in = 1.666ft
56cm = 56/2.54cm = 22.05in = 1.8375ft. 

So from that, You would have 56cm -> 1.8ft -> 20in. for Greatest to Least.
