Answer:
S = 8 
Each side of a face is 8 units.
Step-by-step explanation:
The surface area of the cube is 384 units.
One face of the cube has an area of s^2
A cube has 6 faces 
6s^2 = 384                                 Divide by 6
s^2 = 384 / 6
s^2 = 64                                     Take the square root of both sides
sqrt(s^2) = sqrt(64)
s = 8
