Mistake in determination of x and y component of weight force on inclined box. The angle between the weight and the inverted y axis is theta: the angle of the incline, but since this angle is in the third quadrant the cosine gives the y component of force and sine the x component.
It just happens to work out in this problem since sin45 = cos45, but that won't always e the case.

b is a rise of potential energy, refrain from using "work" as a substitute word for potential energy
