  1. The relative uncertainty in x^n is n times the relative uncertainty in x.
    the relataive uncertainity in the above is 10 percent, so the relative uncertainity in the volume is 30 percent
    Volume=8.0+-2.4 cm^3
    absolute uncertainity=4.8 cm^3

    another way:
    high volume-low volume
    2.2^3-1.8^3= 4.8cm^3
