To use 64 cubes, each edge would have 4 and each side 16. The inner cubes would only be 2x2x2 = 8 cubes without sparkles.

that's it! :)

The larger cube is 4*4*4 = 64 small cubes.
Going across, the two outer cubes have sprarkles, but the two inner ones don't.
Going down, same.
Going the third direction, same.

The small cubes with no sparkles = 2*2*2 = 8

The answer is zero.

Each side of the larger cube contains three rows of smaller cubes that are four cubes in length. Every cube within the larger cube has at least one side that is sprayed with sparkles.

Given that 64=4^3, the larger cube will be a 4x4x4 cube; therefore the "inner" cube will be a 2x2x2=8 cube. This is the answer.

64^(-3)=4

only the cernter have no sparkles, so the inside cube is 2*2*2=8 small cubes
