Question 1128068: parking lot of 4000 feet by 200 feet. The specification requires 8 inches of number 2 stone be place prior to paving. Stone weighs 1950 pounds per cubic yard. How many tons of stone is required for the job?

long, and
high.

.
In other words, ,
so in cubic yards the volume of stone needed is
,
and the weight of that much stone, in pounds, will be
.
An american ton (or short ton) is 2000 pounds,
so in USA and Canada we would say that the stone for the parking lot would weigh
If I had to order it, I would order 20,000 tons.
NOTE:
The metric ton, and the UK long ton are different units.
