Take a look at my WebQuest lesson at:

This is a MS math problem using proportions/ratios to compute the length of the Statue of Liberty's torch arm using the length of her nose. You can do the problem yourself by measuring your nose from the tip to the bridge between the eyes and by measuring your arm length from shoulder to the tip of your fingers. If the length of the Statue of Liberty's nose is 4ft. 6in. what is your estimate of the length of the torch arm?
