depends upon the rock type and how fine it is, but one reference notes that one cubic foot of gravel typically weighs about 100 pounds. So 1 ton has 2000/100 or 20 cubic feet of gravel. A cubic yard is 3x3x3 = 27 cubic feet to the cubic yard.Answer is 20/27 or 0.74 cu yard. I'd round that to 3/4 cubic yard. Other factors that affects the volume of gravel is the moisture content and the grading of the material. ton = 2,000 lbs 1 cubic yard = 2400 to 2900 lbs depending on the nature of the material. Dry random size gravel particles will pack or settle together the tightest resulti â¦ ng in the heavier weight. Dry uniform size particles have more air voids resulting in lighter weight.
âWe are delighted that TGA has approved Breo Ellipta for the treatment of asthma and COPD, providing another treatment option for these patient populations.â. About asthma and COPD. Asthma is a condition of the airways when the muscles become tight (bronchonstriction), swollen and irritated (inflammation).
The U.S. Food and Drug Administration has just announced the approval of a form of new long-term treatment for patients suffering from chronic obstructive pulmonary disease (COPD). The new treatment is an inhaler drug called Breo Ellipta (fluticasone furoate and vilanterol inhalation powder).t is also approved for the treatment of exacerbations in COPD patients. COPD is a form of lung disease that progressively gets worse, it is characterized by the occurrence of chronic bronchitis or emphysema (a pair of co-existing diseases that narrow the airways).
