If you start with 401, then the answer to 401^3 is sure to be bigger than 400.
as i calculate it its 346, its the only cube number that's bigger than 200 but smaller than 400
try maths.com but otherwise its 36
7.93 is one possible answer.
There are two integer answers : 6 and 7. Any value between 5.848 (cube root of 200) and 7.368 (cube root of 400) will satisfy the question.
-- Any number between 5.849 and 7.368 can do that. -- If you only want whole numbers, then 6 and 7 are the ones.

it is 343
How about 73 = 343 or 63 = 216
How about 8 cubed = 512

Any number bigger than 7.37 and smaller than 8.43 will do that. There are an infinite number of them.
How about 7.9?

Any number at all between 5.8481 and 7.368.' 6 ' and ' 7 ' are handy and easy choices.
There is no number that is both smaller than 400 and larger than 600 - if it is smaller than 400 then it must be smaller than 600 since 400 is smaller than 600, similarly if it is larger than 600 then it must be larger than 400 since 600 is larger than 400. Assuming you mean larger than 400 and smaller than 600, then there are 199 such whole numbers than you can cube: 401, 402, 403, ..., 599 can all be cubed, giving 64481201, 64964808, 65450827, ..., 214921799. I guess that the question you are really asking is: What number between 400 and 600 is a perfect cube? The answer is 8³ = 512.
