Hexagonal tiles of side 20cm are used to tile a room that measures 6.25m by 4.85m. Assuming we complete edges by cutting up tiles how many tiles are needed?
A general rule of thumb is to order 10% more tile than your normal square footage to allow for such cuts, etc.
First you need to get the square of the room by multiplying the lenght and the width...6.25m x's 4.85m Then convert that into cm. Next do the same thing on your tile and divid that with your floor and that will give you the # of tiles....I may be wrong here but here we go.... 6.25 * 4.85 = 30.3125 *100 = 3031.25 sq cm ROOM 20 * 6 = 180 sq cm TILE 3031.25 / 180 = 17 tiles I am sure that this is off I would suggest if a room is 12 x 18 ft giving 216 sq ft and a box of tile at a 1.5 x 1.5 at 9 tiles each box at 20 sq ft would be about 11 boxes Another soulution is to goto the hardware store and ask the tile pro to tell you how many you need and give him the measurements lol
