square cub law is simple
you've got a square with sides of 10, right? the area of that square is 10x10 for 100
you've got another square with sides of 100 - the area of that square is 100x100 for 10,000
a cube with sides of 10 has an area of 100 on all faces, and a volume of 1000 (10x10x10)
a cube with sides of 100 has an area of 10,000 on all faces and a volume of 1,000,000 (100x100x100); but a cube with sides of 101 has a volume of 1,030,031, almost a third bigger than the cube with side 100 even though the length of the sides has only increased by 1%
so if you apply that to a human form factor and think of the space a standing body occupies as a rectangular cuboid shape, even modest increases in height drastically increase the bulk of the body itself, which places enormous strain on the biological systems - principally the cardio-vascular system, but also on the skeletal structure including bones, cartilage etc
that's why tall people tend to become light headed or faint when they stand up too fast - the heart can't pump blood hard enough to continue to supply the brain and muscles with oxygen, because the heart is a fairly good pump for average sized humans but if you put it in something the size of a cow, that animal would die of lack of oxygen
