Rating Newest Oldest. Best Answer: Most rocks have a specific gravity of between 2.5 and 2.9. Therefore a cubic meter of rock would weigh 2,500 to 2,900 kg. Of course there are exceptions, but 90% of the rocks found on the earth's surface would be in that SG range.
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.epends upon the rock type and how fine it is, but one reference notes that one cubic foot of gravel typically weighs about 100 pounds.
