    1. The problem statement, all variables and given/known data
    (* to the power of) 20m3 equals to

    2. Relevant equations
    so 1km3 is equal to 1000x1000x1000=10*9
    so 10*9/20m3=50,000,000

    from here i'm confused
    3. The attempt at a solution

    iv attempted to use this method for all the above case yet i continue to get confused help would b warmly appreciated

    Does writing it this way make it any easier?
    [tex]\frac{1}{50\times10^{6}} km^3 =
    \frac{1}{10^{6}}km^3 = 20m^3[/tex]

    What you've done above is correct (other than leaving out the m^3 at the end), i.e.

    What's 1/50? And how would you write 1/106 as a power of 10?
