Total no. of cubes=n^3

hence, 3(5-1)=12 cuts.

SHre  (8 years ago)

as Cube has 3 dimensions i.e L,B,H
now 1 cut on any side divide cube into 2 parts
similarly 4 cuts on any side ( say on L) will divide it in 5 Parts
Hence 4 cuts on B will make ( 5*5 =25 parts ) and 4 cuts on H ( 5*5*5 = 125 )
Therefore
4+4+4 =12 cuts required
