Scale of Leo's model = 2cm : 3 meters

Actual height of the Statue of Liberty in NYC (We have several copies elsewhere!) = 93 meters

For finding the solution, we use the Direct Rule of Three this way:

Scale in centimeters Scale in meters

2 3

x 93

x = Actual height of Leo's model

x * 3 = 2 * 93

3x = 186

Dividing by 3 at both sides:

x = 186/3

x = 62

The correct answer is that Leo's model is 62 cm height.
