Check out:
https://wiki.povray.org/content/Reference:UV_Mapping

The key lines that you want to pay attention to are:

texture {
    uv_mapping

The uv_mapping statement needs to preceed everything else in the texture
definition for it to work.

Also, depending on how you want that box mapped, then yes, there is indeed a box
mapping, but you need to set up the texture specifically to do that, which might
not be a simple task.
