The empire state building is just over 1,450 feet tall. in anticipation of visiting this landmark on your vacation, you create a model of it using blocks.
a. suppose you are making a model where one block represents 2 feet. about how many blocks tall is your model of the empire state building? what is the scale factor?

You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 2 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 2.

Number of blocks=1,450 feet * (1 block/2 feet)
Number of blocks = 725 blocks

Therefore, you would use a model  requiring 725 blocks. The scale factor for the model is 1 block per two feet. 

However, if the workers do outside of what's normally expected, go ahead and tip.
