1,500 square feet (30x50 = 1,500)
30x50 ft
You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
Assuming the room is rectangular - which is usually the case - you simply multiply length x width.
You want a about 8000btu for a room that size
7 x 7 = 49
It depends on how many square feet the box will cover. I found two different brands: one covered 22.93 sqft, the other 17.59 sqft. your room is 12' x 14' = 168 sq.ft so 168 sqft / (22.93 sqft / box) = 7.32 boxes for my first example and 168 sqft / (17.59 sqft / box) = 9.55 boxes for my 2nd example Hope this helps
