Evaluate each of the following and express with an appropriate prefix: (a) (430 kg) ², (b) (0.002 mg)², and (c) (230 m)³.

Solution:

a) $\left(430\:kg\right)^2=0.185\left(10^6\right)kg^2=0.185Mg^2$

b) $\left(0.002\:mg\right)^2=\left[2\left(10^{-6}\right)g\right]^2=4\:\mu g^2$

c) $\left(230\:m\right)^3=\left[0.23\left(10^3\right)m\right]^3=0.0122\:km^3$
