Internally a Warre box is almost 1/2 the volume of a full depth lang. So in theory anyway you only need 1/2 as much treatment, ie, 2 strips a box. But better to err on the side of caution and go with maybe 3.
Undertreating can be a false economy, an extra strip is 2 bucks. Not properly dealing with varroa is much more expensive.
