Answer / santosh k
If a cube is divided into 125 pieces then u can imagine it
as cut into 5 slices horizontally and vertically resulting
in 5x(5x5) pieces. Now if 4 columns are removed than:
5x(5x5) - 4x(5x5) = 5x5 = 25 pieces i.e 1 column.
Something like:
___ ___ ___ ___ ___
|_4_|_3_|_3_|_3_|_4_|
|_3_|_2_|_2_|_2_|_3_|
|_3_|_2_|_2_|_2_|_3_|
|_3_|_2_|_2_|_2_|_3_|
|_4_|_3_|_3_|_3_|_4_|
