Welcome to PF;
It helps if you try to do a bit first, then we can target the specific area you need help.

To get started - you know the equation for the field due to a single charge - you just add them up for all the charges, remembering that [itex]\vec{E}[/itex] is a vector.
Hint: you can use the symmetry of the cube, with the fact that each corner has the same charge, to simplify the problem.
