Try this:
Set the number format of the cell to:
Category: Custom
Type: ;;;

Set the Protection of the cell to: Locked and Hidden
Protect the sheet

Now, copy/paste should only pick up the value and NOT the formula.

Does that help?

This is not the simple question of "I don't know how to hide cells". Is
there any way that I can hide a cell in such a way that even if copied by
another user over to a new sheet, they won't see a formula?

In other words, I believe that even if rows are hidden, cells are locked,
and formulas hidden, with protection turned on, a foreign user could still
drag across the whole region and paste right onto a workbook to see how the
formulas were derived. Am I right, or am I missing some functionality?
