How many tiles measuring 450mm x 450mm do i nedd to cover an area of 6m x 2m?
As has been said you need 60 tiles, however if there is cutting involved the experts advise adding a 10% breakage allowance so consider buying another 6 as spares.
Your answer is 60 tiles (actually about 59 and 1/4 tiles). 1 meter = 100 centimeters = 1,000 mm Area: 6 meters X 1000 = 6,000 mm 2 meters X 1,000 = 2,000 mm 6,000 mm X 2,000 mm = 120,000,000 mm2 Each tile: 450 mm X 450 mm = 202,500 mm2 Number of tiles: 120,000,000 mm2 : 202,500 mm2 = 59.26 tiles or ~59 1/4 tiles. An easier way is to convert the whole thing to meters. That will avoid all the confusing zeros, while the result remains the same (as using inches rather then 1/16 or 1/32. lol).
