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.
Determine the square footage by measuring the length and width of the area and then multiplying the figures. Multiply the square footage by seven to arrive at the number of bricks needed. Divide the number of bricks needed by 1,000 to determine how many bags of mortar to purchase. Brick flooring is laid in much the same way as tile.
