It can be.
Answer = 8. The only small cubes with paint on three faces are those that occupied the corners of the original cube.
The numbers are perfect cubes, so d will also be a perfect cube.
27 of them.
8 if you want it to be 2X2 of cubes, 27 if you want it to be 3X3.
The perfect cubes between 10 and 30 are 27, which is the cube of 3 (3^3). The next perfect cube, 64 (4^3), exceeds 30, while the perfect cubes below 10 are 1 (1^3) and 8 (2^3). Therefore, 27 is the only perfect cube in that range.

3x3x3 cube has 27 cubes. One is in the middle and cannot be seen so the answer is 26.
Answer = 8. The only small cubes with paint on three faces are those that occupied the corners of the original cube.
A 5x5x5 cube consists of 125 smaller unit cubes. When painted on the outside, the cubes on the surface are affected, while those entirely inside remain unpainted. To find the number of painted and unpainted cubes, you can calculate the number of cubes on the surface and subtract the volume of the inner 3x3x3 cube (which contains 27 unit cubes) from the total. Thus, the painted cubes are 125 - 27 = 98, while the unpainted cubes remain 27.
There are 27 1x1cm cubes
273 = 27 x 27 x 27 so...19683
The numbers are perfect cubes, so d will also be a perfect cube.
Three units on an edge, cubed this would be 27 small cubes to the large cube. There are two cuts in the x, y and z coordinates, so this should be six cuts to go from 27 small cubes to one.
