Math CentralQuandaries & Queries


Question from Sara, a student:

A bronze statue is made in two sizes.
The taller statue is 15 cm high and the shorter one is 9 cm high.
The taller statue weighs 3.75 kg. What is the weight of the shorter statue?
Thanks a lot!

Hi Sara,

I just responded to a similar question from Normand. In his question the model of the locomotive was half scale in all three dimensions. In your question the shorter statue is also reduced the same amount in all dimensions (otherwise it would look strange) but not by a scale factor of 1/2. You know the height is reduced from 15 cm to 9 cm, so what is the scale factor? Can you now look at my response to Normand and see how to answer your question?
