20 / 1 = 50 / x.....20 sheets to 1 cm = 50 sheets to x cm
cross multiply
(20)(x) = (1)(50)
20x = 50
x = 50/20
x = 5/2 = 2 1/2 cm (or 2.5 cm) <==

1/20 = .05
 so each sheet is .05 of a cm.
 50*.05 = 2.5 
by multiplying 50 (the number of sheet) by .05 (the height of one card) you get 2.5 the height of 50 cards.
