8 boxes of Pergo Outlast+ 7.48 in cover 157 sq ft, so 11.8 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 151.8 sq ft (15%), or 8 boxes — no extra box here.
With planks running along the 12 ft wall you get about 18 rows across the 11 ft width, the last one about 4.1 in wide, wide enough that the room needs no balancing cut.
