The Delian Problem - Doubling a Cube - is one of three Classical Greek problems.

Using ruler and compass only:

(1) Doubling a cube - construct a cube with a volume which is twice the volume of a given cube.

(2) Trisect an angle - construct an angle which is a third of the size of a given angle.

(3) Squaring a circle - construct a square with the same area as a given circle.
