In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube can also be called a regular hexahedron and is one of the five Platonic solids. It is a special kind of square prism, of rectangular parallelepiped and of trigonal trapezohedron. The cube is dual to the octahedron. It has cubical symmetry (also called octahedral symmetry). It is special by being a cuboid and a rhombohedron.
The cube has four special orthogonal projections, centered, on a vertex, edges, face and normal to its vertex figure. The first and third correspond to the A2 and B2Coxeter planes.
For a cube centered at the origin, with edges parallel to the axes and with an edge length of 2, the Cartesian coordinates of the vertices are
while the interior consists of all points (x0, x1, x2) with −1 < xi < 1.
For a cube of edge length a,
As the volume of a cube is the third power of its sides a × a × a, third powers are called cubes, by analogy with squares and second powers.

These four walls is home. And all to reflect upon. Living through others lives.
Only blackness here in this monotone-life.
Cannot differ his days, cannot control his fate.
"Never" live his lust
"Never" touching the rose
By beauty in safety, his life is set by others, your exile euphony
No need to dream, your world already pictured
No need to reach, your world already given
"Never" life is lust
"Never" touching the rose
Touching the screen makes it so real, it seems so real.
By beauty in safety, his life is set by others, cannot differ his days.
No need to doubts, your truth is always pictured
No need to think, your truth is already given
By beauty in safety, his life is set by others, your exile euphony
No need to doubt, your truth already pictured
No need to think, your truth already given
Never
