Question: I need a formula or step by step help to show my child how to find missing dimensions for example: The scale factor for a model is 10 inches = ________ feet
Model 39.7 in
Actual 11.9 ft


Hi Jackie,

If 39.7 inches in the model represents 11.9 feet then 1 inch in the model represents 11.9/39.7 = 0.3 feet. Thus 10 inches represents 0.3 x 10 = 3.0 feet.
