Imagine a cube, 3x3x3 in size. Each of the 27 segments inside the cube contains a different character including the 26 letters and one space.
The characters are arranged in such a way that A will be next to B, which is next to C etc. They are connected side by side or top and bottom, not diagonally. The space is next to the Z; other punctuation should be ignored.
De-cipher the following code relating to the above cube:
y2b, x3a, y2a, z3c, y1b, x2b, y1b, z2a, x1a, x2c, x3a, y2c, y1b, y1a, x3b, x3a, z1a, y1b, y3b, z3b, y2b, z1c, y1b, x3b, x2b, z1a, y1b, y3b, z3b, z3c, y1b, z1a, y3b, y2b, x1a, y1a, x3a, y3b, z3b, y1b, x2c, x1a, y1a, y1b, y1a, x3b, z3c, z2a, z3c, y1b, z2b, x2b, z1c, y1b, x2c, z3c, y1b, z2b, y3b, z2a, z3c, y1b, y1a, x3b, x2b, z3b, y1b, y3b, z3b, z3c, y1b, x1c, x2b, z1c, y1b, y1a, y3b, y1b, y3c, x3a, z3b, z2c, y1b, x3a, y1a.
