A 12 × 14 ft room (168 sq ft) needs 10 boxes of LifeProof vinyl plank — 184.8 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.

10 boxes of LifeProof 8.7 × 48 in cover 200.6 sq ft, so 15.8 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 193.2 sq ft (15%), or 10 boxes — no extra box here.
With planks running along the 14 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.
