30 square feet / 18 square inches per tile = 240 tiles.
But you should probably buy 264 tiles to allow for 10% waste, and may have to buy the tile in full case lots - check with your supplier.
And you may want to order trim pieces or bullnose pieces for exposed edges.
To determine how many 3 x 9 tiles are needed to cover 30 square feet, first calculate the area of one tile. A 3 x 9 tile has an area of 27 square inches (3 inches x 9 inches). There are 144 square inches in a square foot, so 30 square feet is 4,320 square inches (30 x 144). Dividing 4,320 square inches by the area of one tile (27 square inches) gives approximately 160 tiles needed to cover 30 square feet.
Guess 30 x 30 tile means a tile 30cm by 30cm i.e. approximately 1 foot by 1 foot, in which case the answer is 1 square foot.
Since a 12" x 12" tile is exactly one square foot, the answer should be obvious.
A quarter of one tile (6 ft * 20 ft) will be sufficient!

The best way to figure out how many 13x13 tile will be needed to cover 30 sf of floor is to calculate 13x13/144 give coverage per tile (1.1736), then take 30/1.736 = 25.56 tiles.
To determine how many 3 x 9 tiles are needed to cover 30 square feet, first calculate the area of one tile. A 3 x 9 tile has an area of 27 square inches (3 inches x 9 inches). There are 144 square inches in a square foot, so 30 square feet is 4,320 square inches (30 x 144). Dividing 4,320 square inches by the area of one tile (27 square inches) gives approximately 160 tiles needed to cover 30 square feet.
Guess 30 x 30 tile means a tile 30cm by 30cm i.e. approximately 1 foot by 1 foot, in which case the answer is 1 square foot.
Since a 12" x 12" tile is exactly one square foot, the answer should be obvious.
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.
If it is a 4inch by 4inch (1/3foot by 1/3foot)tile and it covers a 10ft by 10ft area then it will take 900 of these tiles to cover the whole floor. If you walk ten feet on a edge of this floor then you will have to place 30 tiles along this edge. Since the area is a square area then to find the amount of tiles just multiply 30 by 30 to get 900tiles.
A quarter of one tile (6 ft * 20 ft) will be sufficient!

If you're using 30cm x 30cm tile then it cover 900 cm area using 1 tile and your area is 12m x 12m=144m x 100 = 14400cm. Now 14400cm / 900cm = 16.You need 16 pcs of 30cm x 30cm tiles.
Lets do length and width in terms of tiles. The length is 6m/0.2m/tile 30 tiles and the width is 5m/0.2m/tile 25 tiles. Then the area is l X w 30 tiles X 25 tiles 750 square tiles. Since each tile is square, 750 tiles.
