What is the meaning of "4" in "4 ÷ (1-93.75%)"?

What is the meaning of "8" in "8× 4 = 32"? )

The answer is as follows:

Because there are an even number of small cubes on each side of the big cube, the small cubes on the diagonal (the connecting line between the farthest two vertices of the eight vertices of the cube) are all black. If this is a big cube, I tell you, no matter how long the cube is, each layer is four small black cubes. (To be redundant, if each side of a big cube has an odd number of small cubes, like this, except the middle layer is 1, the other layers are also 4).

"1-93.75%" means that if the volume of a large cube is regarded as "1", the volume of a white cube accounts for 93.75% of the total volume, and each layer is the same (odd sides of a large cube cannot be counted like this), then the volume of black on each layer accounts for "1-95". Find "cell 1" by division.

Because each layer has 64 small cubes and squares, the side length is 8(8×8=64), and the side length of the big cube is also 8, so a * * * has: 4× 8 = 32 small black cubes.

"8" in "8× 4 = 32" refers to 8 layers, that is, the side length of a cube.
