We don't actually know how many dimensions there really are. Certain theoretical considerations imply that there are at least 10 or 11, it's just that most of them are "curled up small" and we don't notice them.
That said, a 4D object cannot fully exist in a 3D space. However, a 3 dimensional "slice" of them can exist in that space, just like a 2D "slice" of a 3D object can exist in a 2D space.

What is the difference between 2d 3d and 4d?
i think it is where 2d is flat 3d looks like you can touch it but you cant and 4d is where you can see it and physically touch it
What is a 4D Hypercube?
The 4-dimensional analogy of a 3D cube.
How do you simplify 5c plus 7d-2c-3d?
Group 5c-2c and 7d-3d and it comes to 3c+4d
What is a 4D cube?
The 4th dimension is commonly regarded as time. So a 4D cube could be considered a 3D cube as it exists over time.
