How many yards of sand to fill a 275 gallon oil tank?

To determine how many yards of sand are needed to fill a 275-gallon oil tank, first, convert gallons to cubic yards. There are 27 cubic feet in a cubic yard and 7.48 gallons in a cubic foot. Thus, 275 gallons is approximately 37 cubic feet (275 ÷ 7.48). Dividing by 27 yields about 1.37 cubic yards. Therefore, you would need approximately 1.37 yards of sand to fill a 275-gallon oil tank.
