The sum of the measures of the angles is 180 degrees.
75 + -5w + 125 + 4w + 85 = 180
Combine like terms.
285 - w = 180
Subtract 285 from both sides.
-w = -105
Divide both sides by -1.
w = 105

Is that the whole question? What kind of advantage are we talking about here?
One possibility would be that the 4-inch box has a greater volume (capacity) than does the 3 1/4-in box. If that's the question here, then your job is to calculate the difference in volume. Find the vol. of each box and subtract the smaller from the larger to calculate the "size advantage" or "volume advantage."
