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.
Add all of the rectangles together to get your total square footage to be covered. 4. Read the label on the can to see the maximum coverage and divide your total square footage and round up to the next whole number to find out how many gallons you need. For Example: 20 feet x 8 feet = 160 square feet. Gallon of Paint covers 100 square feet, so 160/100=1.6 gallons.
