The cube of 20 can be written as 
. Split the 20 up into 2*10. Even though we are doing the cube of this value, first do 
and then do 
. Now multiply these numbers together so it is 8*1000=8000. Which is answer choice D. 8000
Since XZ is a common tangent, it is perpendicular to both XW and ZY.
Draw a line parallel to XZ passing through W and intersecting ZY at V.
Then VZ=11, VY=19-11=8.
Calculate WY using Pythagoras Theorem,
