Answer:2764800

Step-by-step explanation:First step is to convert feet into inches:

1 foot = 12 inches

20feet = 20*12=240 inches

8feet = 8*12=96 inches

Now we can calculate total area:

A = height * width

A= 240 * 96

A=23040 inches²

We know the amount per one inch² and we need to find out total number of blades:

1 inch² 120 blades

23040 inches² x blades

Now we cross-multiply numbers:

1*x = 23040 * 120

x= 2764800

There are total of 2764800 blades in the entire law
