Hi, how do we know total there are 8 grey cubes?
1st cube = 1 cube grey
2nd cube = 8 grey cube in total as he want to use at least 5 grey cube. Cause we need Length x Breadth x height all are same. Should use 8 cubes.
FYI, 3th cube should be 27 cubes. It should be in pattern
1st = 1 x 1 x 1
2nd = 2 x 2 x 2
3rd = 3 x 3 x 3
.
