Excuse me, you're mixing up terminology here. Let me explain:

A SLICE is what "Windows" calls a "DOS primary partition",
often just named a "partition".

A PARTITION is a subdivision of a slice. It holds a file
system. It is comparable (but not the same as) what "Windows"
calls a "logical volume inside a DOS extended partition".

To re-express your requirements:

You need one slice covering the whole disk. This slice
should contain three partitions: One for the OS, one for
swap, and one for data. What you will need to do is
basically what Maxim suggested, which is

a) use the "dedicated" approach, which means that you
   don't create a slice, just three partitions on the
   disk, or,

b) go with gpt / gpart, which is okay if FreeBSD will
   be the only OS that accesses the disk(s) in question,
   as I may assume by your statements.

I'm not sure if I understood you correctly. You won't need
to create three slices, just one slice, containin three
