297.632789 m-1 Depending on size of grains, This answer is based on the average size of grains.
That depends upon the substance that makes up the 800 cubic yards: 800 cubic yards of hydrogen weights approx 47.86 short tons; whereas 800 cubic yards of mercury weighs approx 9124 short tons.
800 yards = 731.52 meters.
800 inches = 22.2 yards.
There are: (7*1760) +800 = 13,120 yards
800 meters = 874.9 yards
800 Yards=0.454545455 miles 1 Yard=0.000568181818 miles
800 / 9 = 88.88 sq yards
800 yards.
800lbs = 0.363 tons (3sf)
Yards is a linear measure you can't calculate how much it weighs ... that's like asking 'How much does one mile weigh'. Some times "yard" is used to mean "Cubic Yard" but even then we would need to know what MATERIAL you want to calculate.
