400.
6 x 24 inch tile = 144 sq in = 1 sq ft 400/1 = 400 tiles
375 of them. Get 400.
One 18 inch x 18 inch tile = 1.5 ft x 1.5 ft = 2.25 sq ft.400 sq ft x 1 tile/2.25 sq ft = 177.77 = 178 tiles
There are 12 inches in 1 foot so each tile is 1x1 ft. This means nine tiles will fit along nine ft and twelve tiles will fit along twelve ft The area of this would be 9x12 Which is 108 In conclusion 108 12x12 in tiles will cover 9x12 ft
100 exactly ! Each tile is 4 square feet !
It might depend somewhat on what you need to 'do' to the 400 sq ft.If the area is flat, such as a floor or a wall, it will take 225 of them.

A 6 ft * 12 ft tile will cover 72 square feet.
1.94 sq ft approx.
1^2 = 1X1 = 1 ft
400/1.777 = 225.1 so a minimum of 226. But, in reallife you should allow for 5-10 % for breakages - depending on your level of skill, and any awkward shapes that you might have to cover.
