There is no 'need' for tiles on a house. If you had tiles on your house, then they would need to be waterproof if the function of said tile is to provide weatherproofing. If you just have (let's say) floor tiles on your house, then they'd need to be supported so they don't bend and buckle. If the tiles are to be on the roof, they should be able to handle the heat up there from the sun beating down on them. This question is very likely to be misinterpreted. It should be rephrased, because I'm sure the question in the poster's mind is not anything resembling the question as it was asked, literally.
If these are one inch tiles you need 2160. If the tiles are 12 inch tiles you need 180.
To lay pool tiles, you will need mortar to affix the tiles to the cement pool, you will also need grout for between the tiles and a sponge to clean the tiles.

If you had absolutely no waste you would need 864 tiles. Since tile as large as 20" x 20" generally have a large amount of waste, make sure you add 10% into this number. With that you would need 950 tiles to complete your job.
Tiles are the "square things". Altogether, the tiles make up the floor.
78 feet = 78 x 12 inches = 936 inches. To line one side of this with 16" tiles will take 58 and a half tiles. 26 feet = 26 x 12 inches = 312 inches. To line one side of this with 16" tiles will take 19 and a half tiles. So, you will need to buy 59 x 20 tiles (to ensure that patterns match) = 1,180. If the tiles are plain then you can use one tile to give two half-tiles and will only need 1,141 tiles.
