Answer: 216
Step-by-step explanation:
Since, a cube is a 3D structure,
We can understand this problem by assuming the figure in the coordinate axis.
In which, The cubes in the box along x-axis = 10
Along y-axis = 10
Along z-axis = 10
Total cubes along each x, y, z directions those are not appearing on surface are (10-2), (10-2), (10-2) = 8, 8, 8
Therefore total cubes which are not shown on the surface of the cube= ![6\times 6\times 6 = 216.](https://tex.z-dn.net/?f=6%5Ctimes%206%5Ctimes%206%20%3D%20216.)
Since, the box that are not in the surface are removed.
Thus, the total boxes that are removed = 216
