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)
