####The Delian Cube-Doubling Problem: Now You can Feel it.
This is a classic problem! It looks pretty simple; but it is a fascinating math problem, stretching from 1D through 2D to 3D.
It is proven impossible to double the volume of a cube using (unmarked) *straightedge and compass*. However, with a marked ruler, one can construct the edge of such a doubled cube and thus the whole cube.
Depending on your perspective, please choose either one of the following models.
