    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 lawn
