1 tile = 1.77 of a square foot, 240 Sq.Ft. divided by 1.77 = 135.5 tiles ok
240 square tiles are needed

To determine how many 3x6 tiles are needed to cover 30 square feet, first calculate the area of one tile. A 3x6 tile has an area of 18 square inches (3 inches x 6 inches). Since there are 144 square inches in a square foot, each tile covers 18/144 = 0.125 square feet. To cover 30 square feet, you would need 30 / 0.125 = 240 tiles.
He will need 240 tiles.
1 tile = 1.77 of a square foot, 240 Sq.Ft. divided by 1.77 = 135.5 tiles ok

12X20 = 240 sq feet 12"x12" tiles are 1 sq foot each so must be 240/1= 240
If you mean 20 in x 20 in tiles, the 240 sq ft room is 240 x 144 sq in = 34560 sq in. each tile is 20 x20 = 400 sq in tiles needed are 34560/400 = 86.4 tiles, say 90 tiles
240 square tiles are needed
Each tile is 12 inch x 12 inch = 1 foot x 1 foot = 1 square foot. To cover 240 square feet you would need 240 tiles
Two tiles of size 12 ft x 12 ft will cover 288 square feet and so should be sufficient.
240 sq ft = 240x12x12 = 34560 sq inches Each tikle is 18 x 18 = 324 sq inches Thus you need 34560/324 = 107 tiles
(100*144)/(12*5) = 240 tiles are needed
We don't see the units on the 12x12 tile, but we have to assume it's inches. So each tile = 1 square foot. The room measures 20-ft x 12-ft = 240 square feet. So it takes 240 tiles to cover the ceiling, and another 240 to cover the floor. In order to calculate how many tiles it takes to cover the walls, we need to know the height of the ceiling above the floor.

15x15= 225 16x16=256 So 15.5 x 15.5=240:)
