When one thing is ten times as large as another, it is said to be "an order of magnitude" larger. a hundred times larger is two orders of magnitude. a thousand is three orders of magnitude. by how many orders of magnitude is the empire state building taller than a chair seat?

The empire state building is about 1,500 feet tall while the chair seat is about 1.5 feet

1,500 feet = 1.5 feet x 1,000

Thus, the empire state building is about a thousand times taller than a chair seat.

Therefore, the empire state building is taller than a chair seat by three orders of magnitude.
