But this has been exacerbated by human activities which have led to: 1) an increase in greenhouse gas emissions that causes heat to remain trapped within the troposphere, and 2) a decrease in ozone in the stratosphere, causing less sunlight to be absorbed by the ozone layer, resulting in a cooling of the stratosphere.
When measuring for floor tile the rule is: Length x Width + Waste = Amount Needed. Waste Factor will vary based upon tile size, layout, configuration of room, patterns, etc. Typical waste factor is about 10%. Add 15% for tile being installed diagonally or for a room with lots of jogs and corners.
Area to be covered 1000 tile size 2ftx2ft Area covered per tile (sq ft) 4 consider wastage 5% No of tiles in a box 4 No of tiles required 263 No of boxes required (4 tiles per box) 66 you would need 263 tiles of size 2x2 ft visit www.econstructionmart.com for more information on tiles price, features and options.ost tiles are sold by the carton with x amount per carton so you will have to round up to the closest carton. EX. 7 ft 6 in x 5ft 3in = 7.5 x 5.25 = 39.37 SQ FT add 10% 3.93 = 43.3 SQ FT 2x2 = (x36) = 43.3 x 36 1,558.8 pieces obviously there is a lot of rounding up and down in tile because there will always be waste.
