Why does BMI have units of kg/m^2 when we are three dimensional? Wouldn’t kg/m^3 or g/cm^3 be more accurate?

No. Healthy humans of a similar height should have roughly similar weights. We are all mostly water and all water weighs the same. There is some genetic variation in fat distribution and muscle development, but we should all be fairly average.

A male human can only increase his lean mass by about 10% through weight training without using steroids. So the whole “I carry a lot of muscle” argument is self denial.
