This is not the first time that this type of rumor about the iPhone 7âs home button surfaced. Back in June, Forbes picked up an online rumor claiming that Apple will be upgrading the home button by making it more sensitive to touch.
Answer: A cubic foot of top soil weighs in the neighborhood of 75 - 100 pounds. There are 27 cubic feet in a cubic yard. Hence, one cubic yard of top soil weighs between 2025 and 2700 pounds. Moisture content would make this figure variable.
These conversions are based on an estimate that the surface 6 inch layer of soil over the area of an acre weighs 2,000,000 pounds. The actual weight depends upon the soil bulk density which commonly varies from about 1.3 to 1.7 g/cc. For example, a cubic foot of water weighs 62.4 lbs. If the bulk density of a soil were 1.3 g/cc (1.3 times heavier than water) then the soil would weight 62.4 x 1.3 or 81.1 lbs/cu. ft. on a dry weight basis.
