Answer
a) $1\times10^{6} m^{2}$
b) $1\times10^{-6} m^{3}$
c) $1\times10^{-9} m^{3}$
Work Step by Step
a) Using the conversion factor of $1 km^{2} = 1\times10^{6} m^{2}$, therefore we simply multiply 1 by $\times10^{6}$.
b) Using the conversion factor of $1 cm^{3} = 1\times10^{-6} m^{3}$, therefore we simply multiply 1 by $\times10^{-6}$.
c) Using the conversion factor of $1 mm^{3} = 1\times10^{-9} m^{3}$, therefore we simply multiply 1 by $\times10^{-9}$.
