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.
1) Figure out the square footage to be covered. 2) Multiply the square footage by the depth desired to get the cubic footage. 3) Divide the cubic footage by 27 to get the cubic yards needed. Example: A rectangular landscape bed is 12' 8 long and averages 5' 6 wide and the depth desired is 2 Â½ deep.
