Answer:
<h2>He could use the medium box.</h2>
Step-by-step explanation:
Notice that the umbrella is 37.5 inches long.
If you observe, each box doesn't have 37 inches wide, however, they are tridimensional figures, which means they have a certaing height.
So, the smalle box is too small to fit the umbrella.
But, the medium box is perfect, because it has 27 inches wide and 27 inches height, which is enough to fit the umbrella. These are the best dimensions to send the umbrella.
Therefore, the medium box is the answer, the one that has dimensions 27x14x27.
