Ans: 322
Num of cubes from 1 to 300 = 6 (1,8,27,64,125,216)
Num of squares from 1 to 300 = 17 (As 18*18 is more than 300)
Here 1 is a square as well as a cube.
Hence total numbers not in the series = 6+17-1 = 22
So the remaining 22 numbers in the series beyond 300 will be like 301,302,...322 (As 324 is the next square which is for 18)

Ans: 321
As 64 is also a cube and a square, the answer will be 321
