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.
Answer:
12
Step-by-step explanation:
a=3b
b=2c
c=4d
a*c/b*d = (3(2(4d)))*(4d)/(2(4d))*d
= 96d^2/8d^2
= 12
