S = 4 * π^2 * (R + r) * (R – r)
the place R is the outer radius, r is the inside radius, and S is the floor space.
To approximate the floor space, we have to combine the world of the torus utilizing numerical integration. We are able to use a small grid of patches to approximate the floor space.
Suppose we use a grid of 100×100 patches. Then, the floor space is approximated utilizing the next method:
