my approach.. go for the cubes which wont be on the top layer mean they wont be painted
3x9x14 mean for every side there are 2 layers exposed on opposite sides.
which means 1x7x12 = 84 cubes wont be painted.
now painted cubes = 378-84 => 294
i think m rite!!
o yeah!!!
When a solid wooden cube is painted blue and then cut into 27 smaller cubes, the original cube's surface area is divided among the smaller cubes. Since each side of the larger cube is painted, the outer layer of the smaller cubes will be blue. Out of the 27 smaller cubes, only the 8 cubes in the center do not have any blue paint, while the remaining 19 have at least one face painted blue. Therefore, the fraction of the total surface area that is blue is ( \frac{19}{27} ).
24 of them
It depends on whether they are stuck together so as to form a 1x1x6 cuboid or a 1x2x3 cuboid, or a 1x1x2 cuboid on top of a 1x2x2 cuboid. Each of these will give a different answer.
If the dimensions of the cuboid are also in cm then (16*4*8)/(2*2*2) = 64 cubes
Coal cubes: 0. Sugar cubes: 0 Painted cubes: maybe some of them.
8
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.

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?
conclusion of cuboid
Sweet, granulated, white, cuboid.
no.of cubes made=volume of cuboid/volume of cube i.e, (21*27*8)/(3*3*3) = 4536/27 = 168 cubes

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.
