Detectable warning tiles, also known as tactile paving, are required by law in several areas to assist visually impaired individuals in navigating public spaces. In the United States, the Americans with Disabilities Act (ADA) requires detectable warning tiles at transit platform edges, curb ramps, and vehicular ways. They are also commonly used in public areas such as at crosswalks, pedestrian crossings, and at the edges of stairways. In other countries, similar regulations or guidelines may be in place to ensure accessibility for visually impaired individuals in public spaces.

ADA detectable warnings are required in many areas of public spaces such as pedestrian crossings, escalator approaches, curb ramps, transit platforms, parking areas, stair landings, and many more.
* Calculate how many tiles you need to place for the required width. (Divide width of sideway by width of tile; round up if necessary.)* Calculate how many tiles you need to place for the required length. (Divide length of sideway by length of tile; round up if necessary.) * Multiply the number of tiles long, times the number of tiles wide. This gives you the number of required tiles. (Some additional adjustments may be required; not relevant for this problem.) Divide that by the number of tiles per box, to get the required number of boxes.
It depends on the units used for measuring the tiles. Obviously, the number of 18 inch x 18 inch tiles required will not be the same as 18 cm x 18 cm tiles. And if there were 18 yard x 18 yard tiles, you would need only 1.
There are 100 cm in a meter, so the wall is 400 cm X 1200 cm. If there is no gap between the tiles: then 400 cm / 4 cm = 100 tiles, and 1200 cm / 4 cm = 300 tiles. So 100 x 300 = 30,000 tiles.
It depends on the dimension used for measuring the tiles. Whether they are 12 in x 12 in or 12 cm x 12 cm will make a huge difference to the number of tiles required!
