how many cubic feet in a ton of pea gravel
So 1 ton has â¦ 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.Pea gravel for instance contains all particles of a specified size, say, 1/4 inch.bout 120 lb Just for reference: 1 cubic foot = 6.25 gallons (imperial), I gallon of water weighs 10 lb, so a cubic foot of water weighs 62.5 pounds. This means the specific â¦ gravity of gravel is 120/62.5, or a bit less than 2.
