Besides applying the squaring method on the two-dimensional plane with the midpoint of Germany, it can also be applied to three-dimensional space. This makes it possible to calculate the
midpoint, as well as the gravity point and the outermost point of bodies.
For this, the body is no longer divided into squares but into many equal-sized cubes. The determination of the midpoint is then again made by identifying the cube with the smallest total distance
in relation to all other cubes (in 3D space). Similarly, the calculations for the centroid and the outermost point are conducted.
