A number taken to the power 3 is said to be cubed, so 
is called "
cubed." This terminology derives from the fact that the
volume of a cube of edge length
is given by 
, hence the operation taking a cube's edge length to its
volume is known as "cubing" and the quantity 
derived from 
by cubing is known as "
cubed."
