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.
Measure the square footage of the floorspace. To get the square footage, multiply the length by the width of the garage interior. For example, for a garage measuring 20 feet by 24 feet, you would calculate the square footage with the following equation: 20 x 24 = 480 square feet. Multiply the square footage by the height of the ceiling to determine the total cubic footage of the space to be heated.
