as i calculate it its 346, its the only cube number that's bigger than 200 but smaller than 400
If you start with 401, then the answer to 401^3 is sure to be bigger than 400.
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.
The number 6 has a cube (6 x 6 x 6) equal to 216. The number 7 has a cube (7 x 7 x 7) equal to 343.
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.

it is 343
How about 7.9?
The only cubic number between 400 and 600 is 8 x 8 x 8 (83) = 512.

How about 8 cubed = 512

How about 73 = 343 or 63 = 216
941 over 400 is already reduced as a fraction. It can be reduced to a mixed number as 2141/400
300/400 = 3/4 or 0.75 (or it could be (300/20)3 = 3375)
