Raised to the third power
I believe the answer is:
cubed
'raised to the third power' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cubed that I've seen before include "One is so unchanging" , "(Of number) multiplied by its own square" , "Like some sugar" , "Diced - raised to the third power" , "To the power of three" .)
