Question

The Empire State Building in New York City is 1250 feet tall. It took 30,000 workers only 1 year and 45 days to build, which is a record for a skyscraper. On a scale model of the building, the height is 25 inches.

What is the scale of the Empire State Building model?

Answer 1

The scale is 1:600

Explanation:

To calculate the scale you have to divide the two values of height for this case, but in the same units. So 1250 feet is equal to 15000 inches. Dividing 15000 by 25 is equal to 600, that is the scale. 1:600.

Answer 2

Explanation:

1250 feet *12 inches per foot : 25 inches

15000 inches : 25 inches

Scale = 600:1 in other words 600 inches of the building represents 1 inch of the model.

If you want the scale to be feet of building per inch of the model, then don't multiply by 12

1250 feet : 25 inches

25 feet of building: 1 inch of the model.
