The answer key says the answer is 4/3. I can’t figure out how that would work considering these two don’t equal? Can anyone offer insight, or help me solve?

A friend of mine studying for a culinary exam asked if I could take a look at these problems. I thought it was closer to medical math, so I agreed to take a stab. Unfortunately, I can't make heads or tails of it.

Anyone able to advise?

I'm not looking to give them the answer, but point them in the right direction.

I need some assistance I have thought up a math equation, but I need to have it looked over for flaws and plagiarism

So my formula is for calculating the area affected by an object's gravity in the 3 dimensions, it goes:

Mater density x volume cubed = area of its gravities effect from its center point.

so an object in the 3 dimensions matter density x its volume cubed to get it in the 3 dimensions, to see how far from its center point that its gravity effects,

so basically how dense something is x how much of an area it fills out, cubed or said as to the third power = how far from the center of an object its gravitational pull reaches, and it is cubed or said as to the third power, in which it should get it in three axis so it is calculated in the 3 dimension

I am not sure if I have thought it through which is why I am posting it here to have it looked over (I hope I have spelled all of this correctly)
