A 12 × 12 ft room (144 sq ft) needs 9 boxes of Pergo laminate — 158.4 sq ft with the standard 10% waste allowance.
About 20 rows across the largest area, last row ≈ 1.1 in wide — trim the first row too so both edge rows match.

9 boxes of Pergo Outlast+ 7.48 in cover 176.7 sq ft, so 18.3 sq ft is left after the 10% allowance. That's half a box or more — enough to keep for repairs without buying a spare.
Laid on a 45° diagonal the order rises to 165.6 sq ft (15%), or 9 boxes — no extra box here.
With planks running along the 12 ft wall you get about 20 rows across the 12 ft width, the last one about 1.1 in wide — rip the first row narrower too so both edge rows match.
