I’ve been struggling all day what does math

I don't understand the question either. The only answer I can think of is possible that the volume would be entered in the unit cubed. By that I mean: 4 in.^3  while surface area I think would just be in.^2 (squared). I'm not 100% sure that is what they are asking but if it is this should be the answer. Hope it helps.

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3

Ithink ghe answer to this question is b just trying to others
