A 6 x 9 room has 54 Sq. Ft. There are 4 6x6 tiles in a square foot. 4 x 54 = 216 tiles.
12 tiles by 18 tiles or 216 tiles total
24 of them.
Is the room 10 by 6 inches? If so you need 5 12 inch tiles. If it is 10 by 6 feet then the answer is 60.

36 tiles. First you have to convert 20 inches to feet. There are 12 inches in a foot so 20/12 means you have one and two-thirds length tiles. Then, you have to figure out the lenght of the sides of the room which is the square root of 100 sq ft. which is 10 feet long. Now, you have to figure out how many tiles it will take to do one length of the room by 10/one and two-thirds which is 6 tiles. Finally you have to multiply the length times the width to get how many tiles it takes to fill the room by 6*6=36 tiles
Take the are of the room and divide it by 6 and there's your answer.If the room is 8 square feet you would need 32 tiles.If the room is 8 by 8 feet you would need 256 tiles.
6 tiles that are 12 ft x 12 ft should be enough.
Assuming you mean 12 by 12 inch (or 1 by 1 foot) tiles, and a 6 by 6 foot room, and also assuming you just want to cover the floor and none of the walls, then the answer is 36, which is the area of the floor in square feet.
Area of room = 5' * 6' = 30 square feet. Assuming the tiles are 12 * 12 square inches (not sq cm) then the area of each tile is 1 square foot and so 30 tiles are needed.
48 will cover it, get 52 in case of breakage.
60 square feet would be 60 one foot square tiles. Get 5 or 6 extra for breakage.
