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 \(1km^{3} = (1000m)^{3}\)= \(1000000000m^{3}\). = 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.
