The area of the room is 370 sq ft = 370*12*12 sq inches
So number of tiles required = 370*12*12/(14*14) = 271.84
that is 272 tiles would be required.
However, that answer is good only for a mathematical exercise. In real life, you will not be able to use up all the off-cuts; there will be some breakages etc. So you should allow at least 5% more tiles.

18*18 = 324 tiles.
Assuming none are broken during the installation process, 64 full tiles will be required.
12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.

Each tile will cover 100 square inches. 12,000 square feet is 1,728,000 square inches. You will need 17,280 tiles.
Each tile covers 4 square feet. Which means you need 200 tiles to cover 800 square feet, plus spoilage.
It should take about 825 1 foot square tiles to cover a floor with those dimensions. This assumes roughly a 10% waste factor.
18*18 = 324 tiles.
