We are given that:
Model [length = 35 cm; wingspan = 66.9 cm; height = ?]
Actual [length = 21 ft 1 in = 6.43 m; height = 2.74 m; wingspan = ?]
We can solve for the height of the model plane using the given values of the actual plane and by ratio and proportion:
35 cm / height model = 6.43 m / 2.74 m
height model = 14.9 cm
We can also solve for the wingspan of the actual plane:
35 cm / 66.9 cm = 6.43 m / wingspan actual
wingspan actual = 12.30 m
So we can see that the model is:
6.43 m (100 cm / m) / 35 cm = 18.37
18.37 times smaller than the actual plane
