The structural limitation of a baggage compartment is 50 lb/ft2. A load has a mass of 320 kg and has to be distributed over an area of at least:

  • A

    14.11 m2

  • B

    1.31 m2

  • C

    0.76 m2

  • D

    6.4 m2

As the answers option in m2 so we need to convert the limitation from lb / ft2 to kg /m2.

1 lb = 0.453 kg
50 lb = 0.453 x 50 = 22.65 kg
According to limitation we can fit 22.65 kg in one square feet.
Now we need to know how many kg we can fit in one square meter.
1 m2 = 10.76 ft2
Kg that can fit in square meter = 22.65 x 10.76 = 244 kg / m2
To fit the package of 320 kg we need 320 / 244 = 1.31 m2
