(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(* to the power of) 20m3 equals to

a)2x10-8km3

b)2x10*6cm3

c)2x10*5dm3

d)2x19*9mm3

2. Relevant equations

ok

1000m=1km

so 1km3 is equal to 1000x1000x1000=10*9

so 10*9/20m3=50,000,000

1km3/50x10*6=20

from here i'm confused
