A total of eight tiny conducting spheres, each carrying a charge of -110 nC, are placed one each at the corners of a cube 1.2 m on a side. Find the potential at the center (in V).

Just add up the eight potentials.
Use symmetry for E.

I understand, but how do I find the potential to begin with?

[tex]V=\frac{q}{4\pi\epsilon_0r}[/tex]

Just a Clarification

should leave the q as neg. and nC or convert to C and make positive?;
