Formulas:
Surface Area of a Box = 2(L*W) + 2(L*H) + 2(H*W)
Volume of a box = L * W * H

(1) The volume of the box is 20.

20 = L * W * H

No way to know what Length Width or Height are, so we can not determine the SA.

Not Sufficient.

(2) The base of the box is a square.

W = L

No way to know what the Height is. SA can not be determined.

Not Sufficient.

(1) and (2)

20 = L * W * H and W = L

Surface Area of a Box = 2(L*W) + 2(L*H) + 2(H*W)

We still don't know what the measurements are of Length Width or Height, so we can not determine SA.

Not Sufficient.
