Cube root solution expressions involve the real cube root of a real number, while if all three solutions are real numbers then they may be expressed in terms of the complex cube root of a complex number. Quartic equations can also be solved in terms of cube roots and square roots. The calculation of cube roots can be to traced back to Babylonian mathematicians from as early as 1800 BCE. In the fourth century BCE Plato posed the problem of doubling the cube, which required a compass-and-straightedge construction of the edge of a cube with twice the volume of a given cube;
The Cube (film) and this is what his afterlife is like, the Man is visited by a scientist (William Osler) who asks the Man to define reality for him. When the Man claims that the hammer doesn't exist, the scientist proves him wrong by throwing the hammer at one of the cube's walls causing a hole in it. Arnie reprimands the scientist for breaking the wall and gives him his hammer back while he gets the wall fixed. Upon being unable to convince the Man, the scientist leaves hoping that the Man rots in the Cube. Arnie fixes the hole and leaves stating
