The correct answer is the second option down, s =
![\sqrt[3]{V}](https://img.qammunity.org/2019/formulas/mathematics/high-school/8ng6y2czujg2w4gun9sl5u8xzgpxirldbo.png)
.
This is because in order to get the variable s by itself (solve for the variable s), we have to perform the inverse operation of cubing the variable, which would be taking the cube root of the variable. This is similar to the way that you divide when you are trying to undo multiplication when solving simple equations.
Hope this helps!
