If anyone doesn't understand the math, just do it intuitively. Humans are actually quite good at spacial perception and imagination.
The issue becomes more egregious and easier to see the bigger the tonnage separation is. In your mind, cut apart a 30 ton mech and fit it into a 90 ton mech, can you fill that 90t mech with 3 30t mechs or do you need 5 30 ton mechs? It gets worse when you compare a 25 ton mech with a 100 ton mech, or a 20 ton mech with an 80 ton mech, you should be able fill the larger mech with 4 smaller mechs so why does it take more around 8?
My suggestion is: make the mech look like how much they weigh. Mech size is too important to use as a balance point. If this has the effect of making mechs like the marauder (hate), crab/king crab, dire wolf, warhawk (lol), timber, ebon, jenner, raven, dragon, etc.. better because their design prioritizes minimizing front profile, then so be it, let the meta change. At the very least, mech design will actually matter instead of having well designed mechs being inflated for "target size" balance.
