square last year, cube next year implies difference between both is 2.
possible cubes = 1,8,27,64,125
substacting 2 from above cubes = -1,6,25,62,123
out of this only 25 is a square.
so last year age was 25 and next year age is 27 and present age is 26 and next cube is 64 which will be attained after 64-26 i.e 38 years
