I am assuming that your question states that the top and sides are painted red but the bottom isn't.
If so, the answer is:-
There are no cubes with 4 faces painted, the most that can be painted is 3 for the ones on the corners.
There are 4 corners at the top of the cube that will have their top and 2 sides painted. Therefore there are 4 cubes with 3 painted.
The cubes at the corners on the second and third row down will have 2 faces painted, as will the middle cubes on the top row so there are 12 of them in this puzzle.
The cube in the middle of each painted face will have just one face painted so this is 5 (assuming the bottom isn't painted). The cubes in the middle of the bottom row will also have one face painted. This brings the total to 9
That is the total of cubes that have paint on them... 4+12+9 = 25
There are 27 cubes in your puzzle so only 2 have no painted faces. The cube right in the middle and the cube in the middle of the bottom layer.
0 sides are not painted! So all the cubes have three faces painted!
How many smaller cubes are not painted at all if a cube is painted green on all sides & cut into 64 cubes of equal size?
There are several 3D shapes that fit together to form larger structures. Some examples include cubes, which fit together to create a larger cube, and tetrahedrons, which can be arranged to form larger tetrahedron structures. Additionally, octahedrons and icosahedrons can be combined to create larger shapes as well.
Coal cubes: 0. Sugar cubes: 0 Painted cubes: maybe some of them.
Yes, 81 cubes can be arranged in a flat pattern of 9 columns of 9 cubes.
The entire outer layer is painted so an 8x8x8 block inside isn't painted. Zero. All cubes are painted on at least one side and the 10x10x10 cube is painted on all sides. It's a 10x10x10 cube meaning there are 1000 cubelets. Ones on the inside too. So 8x8x8 = 512.
All the little cubes except the one at the middle will have 1, 2 or 3 faces with paint on them, ie 26 of them will have some paint on them: 0 faces painted - 1 cube 1 face painted - 6 cubes (the centre ones of each side) 2 faces painted - 12 cubes (the ones in the centre of where two sides meet) 3 faces painted - 8 cubes (the ones in the corners).

There is no limit to the number of cubes which can be arranged on top of a rectangular prism.

54
Assuming that the cubes are 1x1x1, there will be one thousand cubes in the larger cube.
