Garaga Surendra Kumar  (9 years ago) Best Solution

Volume of cube of dimensions 7 7 6 is 7*7*6=294
If it were to look hollow the imaginary inside cube volume is to be deducted
which is (7-2)*(7-2)*(6-2)=100 (Here 2 is deducted because the inside cube which has to be hollow is 2 cubes more on every dimension)
so minimum number of cubes required to make hollow cube is 294-100=194 cubes
