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.
You want a house and a child but you don't want a man.
You'll live off the state as long as you can.
Claim you're equal with your feminist wit.
If you are you'd better act like it.
With a glass plate in your stomach,
everyone will look at you
The only woman in the world,
to have a womb with a view
Men are the evil, women are good.
You joined the CND just like you should.
Greenham Common the new Babylon.
Campaign all you want they'll still drop the bomb.
Burn your bra then whine for support.
Independence is a thing that can't be taught.
Live was busy for the little girl.
