Abstract

Using compasses and two marked straight edges a construction can be made for the cube root of two, which effectively produces the side of a cube having twice the volume of a given cube. It is also shown how to construct the cube root of a random quantity. The methods use the Archimedes construction for trisecting an angle and are theoretically perfect.
