1. What is the scale factory of the model?

2. Find the actual length of the east side of the building.
3. Find the actual length of the south side of the building.
4. What is the actual perimeter of the base of the building? How does this relate to the perimeter of the
base of the model?

5. How much floor space is there on one floor of the actual building? How does this relate to the amount of floor space on one floor of the model?
