It depends. Do all the cubes need to be equally sized? A cube has 6 sides, or faces. 2,000 divided 6 is 333.3. So, yes, it could be possible if some of the cubes are divided into thirds. However, if all the interlocking cubes need to be equally sized, then no, it wouldn't be possible. It all just depends.
The total number of smaller cubes used to construct a cube must be a perfect cube number. Since 2000 is not a perfect cube, it's not possible to construct a cube with exactly 2000 smaller interlocking cubes. ;
A cube with 2000 interlocking cubes cannot be constructed, as 2000 is not a perfect cube. The nearest perfect cubes are 1728 and 2197. Therefore, it is impossible to create a cube from precisely 2000 smaller cubes.
