Answer:
-10
Explanation:
First...
A cube root is to find a number that if multiplied three times by its self equals this number. (sorry a little confusing)
Next...
Forget about the negative for a little bit and look at it.
10*10*10=1000
Finally...
If 10 cubed is positive 1000 then -10 cubed is -1000.
So the answer is -10.
