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.
Counting the number of tiles. Now that you have the area of a single tile, all you need to do is divide one sq. meter by this area and you will get the number of tiles. So for the 20x20 cm tile the calculations are going to look like this: 1 sq. m / 0.04 sq. m = 25.herefore, the tile of 20x20 cm size has an area of 0.04 sq. m. If the tile size is 30 cm by 60 cm, the calculations indicate 0.3m x 0.6m=0.18 sq. m. For the tile that is 12,5cm x 120cm the area is going to be 0.125m x 1.2m=0.15sq.
