Explanation: Hi! here we have 1.4×10^9km^3 and want to write this quantity in meters.
First, a kilometer is one thousand meters, so 1km = 1000m, so [tex]1km^{3} = (1000m)^{3}[/tex]= [tex]1000000000m^{3}[/tex]. = 10^9 m^3
so changin this in our quantity we get 1.4×10^9km^3 = 1.4×10^9*10^9 m^3=1.4×10^18m^3
and there you hace the original quantity written in meters.
