Usingthe heights,we find a scalingfactorof:

.

You can use a scalingfactorto makea model.

Example 6

Dougis makinga modelof the Statueof Liberty. The real statuehas a heightof

feet and a nosethat is

feet in length.Doug’s modelstatuehas a heightof

feet. How long shouldthe noseon Doug’s modelbe?

First find the scalingfactor.

To find the lengthof the nose,simplymultiplythe heightof the model’s noseby the scalingfactor.

In inches,the quantitywouldbe:
