The conversion factor between the unit in meter and that of kilometer is that, 1 kilometer = 1000m
For the given above,
(288 m³) x (1 km / 1000 m)³ = 2.88 x 10^-7
Thus, 288 m³ is also equal to 2.88 x 10^-7 km³.

Explanation:
They also have a larger number of valence electrons, and are already close to having a complete octet of eight electrons.
