You buy a 1:1000 scale model of the Statue of Liberty during a trip to New York City. The height of the model is 9.3 centimeters
yanalaym [24]
The Statue of Liberty is 93 meters tall. If you have a model that is 9.3 centimeters and is 1/1000 the size of the actual Statue, then you would multiply the model by 1000 to get 9,300 centimeters. To get this number in meters, you would divide your result by 100. This would give you 93 meters.

Sorry if the explanation is worded poorly, the answer is 93 meters.
