In practice you will use more tiles than the equivalent area of the room. A 15 foot strip of tiles will require 15 times 12/13 = 13.846 tiles to cover it. This will have to be rounded to 14 tiles. That means that the 15 foot by 15 foot room will require 14 times 14 tiles = 196 tiles to cover it. And that's if you don't drop and break any or mess up one or more cuts.

Let g= no green tiles and r = no of red tiles At beginning r + g = 15 At end r = g - 2 Add back the 5 red tiles and then r = g -2 + 5 = g - 3 Substituting g-3 for r in original then g-3 + g = 15 2g = 12 g= 6 r= 15 - g = 15 - 6 = 9 No of red tiles = 9; green tiles = 6
If this is for an actual tiling job, the answer is 225. First, convert feet into inches. 1 foot = 12 inches. 24 * 12 = 288 inches So your garage is 288 inches by 288 inches. 288 inches / 19.5 inches = 14.77 So you would need 14.77 tiles across and 14.77 tiles deep. Since you are buying whole tiles, you have to round up. So it would be 15 tiles x 15 tiles. 15 * 15 = 225 tiles. Since many of the tiles have to be cut (0.77 of a tile), it is possible to use the other (0.23) as part of the flooring and get away with a few less tiles, but that's not practical in a real tiling job. It would look terrible.
Whom ever wrote this problem, did not give the unit of measurement (yards, feet, meters, etc.) so, I am going to presume that the 12 by 12 tile is in inches, and the 15 by 15 is in feet. If my presumption was correct the answer is 15 tiles. Because a 12 by 12 tile is = to 1 square foot. How many 1's fit into 15? 15! Well, not exactly..... You need to multiply 15 X 15 to get the square footage and that will give you the number of tiles needed since the tiles are 1 ft square. 15 x 15= 225. So you need 225 tiles. And add extra tiles for breakage...
Area to be covered: 15 x 16 = 240 square units Area of tile = 12 x 12 = 144 square units Number of tiles required = 240/144 = 1.66... . So 2 tiles will be sufficient.
3*5 = 15 tiles.

120"*120" is 14400 sq. in. 15"*15" is 225 sq. in 14400/225=64 tiles..
Each 16-inch square tile covers 11/3 ft* 11/3 ft = 17/9 sq feet. Area to be covered = 15 ft * 20 ft = 300 sq feet. So, minimum number of tiles required = 300/(17/9) = 300*16/9 = 168.75 or 169 tiles. That is the mathematical answer. In real life, though, the answer will depend on the extent to which off cuts are reused. While 15 tiles will do the length, you will require 12 tiles to do the width, making a total of 180 tiles in all. 169 tiles will result in a part of the area being a mosaic of tiny pieces.
if tiles are 15 inch x 15 inch that is 225 sq in400 sq ft = 400x 144 = 57600 sq inyou need 57600/225 = 256 tiles

Because of its toughness, a glazed ceramic tile countertop will outlast a plastic laminate counter. Countertop tile comes in such a variety of color and patterns that you can make your kitchen as elegant or as simple as you choose. The following basic steps will guide you to a beautiful finish. 1. Measure the area to determine how many tiles you need. Make sure all tiles come from the same manufactured lot number. 2. Cut a layer of ¾-inch exterior plywood to fit the countertop area to be created. 3. Cut out a hole for the sink. 4. Cut a sheet of backer board for the backsplash. Apply silicone caulk along the backsplash where it will join the countertop. Screw the backsplash onto the countertop. 5. Place construction adhesive on the cabinet frame and screw the countertop onto the cabinet base. 6. Staple a moisture-resistant membrane to the plywood. Use either 15-pound roofing felt or 4-mil polyethylene. 7. Apply a layer of adhesive, called thinset, to the membrane using a notched trowel. 8. Lay cement based backer board onto the thinset and attach with screws to the countertop. Start with larger sheets up to the edges of the sink cutout, then add narrow strips in front and back of the cutout. 9. Tape the seams with fiberglass mesh tape. 10. Without using adhesive, lay out the tiles in the desired pattern on the backer board. Try to minimize the number of tiles you have to cut. Allow for the width of the grout joints. Remember to allow for a grout seam between the edge tile and the first row of full-size field tiles. 11. Mark guidelines by snapping chalk lines onto the backer board. 12. Apply adhesive to the backer board . Following the chalk lines, place the tile onto the adhesive. 13. Place a tile spacer on the corner of the tile, then continue laying the tiles. 14. Install the edging tile in the same manner as the flat tiles. 15. Apply adhesive to the back of the tiles, then press them in place on the backsplash. 16. Let the adhesive set overnight before applying the grout. 17. Using a float or squeegee, apply the grout, moving diagonally across the joints. 18. When the grout is firm, use a damp sponge to clean the tile surface. Then strike the joints to create slightly recessed seams. 19. Clean tiles with a damp sponge, being careful not to disturb the grout. 20. Allow the grout to harden for several days, do a final cleaning of the tiles with a special tile cleaning solution, and then apply a grout sealer.
