What is a cubed number that = to 8000

$${root3}{\left({\mathtt{8\,000}}\right)} = {\mathtt{20}}$$

Remember that a cube number is a number that is multiplied by itself 3 times. In this case, the answer is 20 because:

$${\mathtt{20}}{\mathtt{\,\times\,}}{\mathtt{20}}{\mathtt{\,\times\,}}{\mathtt{20}} = {\mathtt{8\,000}}$$

Thanks GoldenLeaf.  That is a good answer.
