A 12 × 12 ft room (144 sq ft) needs 8 boxes of LifeProof vinyl plank — 158.4 sq ft with the standard 10% waste allowance.
About 17 rows across the largest area, last row ≈ 4.3 in wide — trim the first row too so both edge rows match.

8 boxes of LifeProof 8.7 × 48 in cover 160.5 sq ft, so 2.1 sq ft is left after the 10% allowance. That's less than half a box, so buy one spare box from the same dye lot if you want planks for future repairs.
Laid on a 45° diagonal the order rises to 165.6 sq ft (15%), or 9 boxes — 1 more box.
With planks running along the 12 ft wall you get about 17 rows across the 12 ft width, the last one about 4.3 in wide — rip the first row narrower too so both edge rows match.
