A yard of concrete weighs two tons, so 28 yards is 56 tons.
25 Yards of concrete
how much tensile strength of M20 grade concrete at 28 Days
3.5 to 4 yards, depending to some extent on where you live and building codes. 6" uniform thickness would require around 3.5 yards.
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
curing time of concrete 14-28 days
25 Yards of concrete
you would need 37.33 yards of concrete or 38 to be safe
28 yards is 84 feet (3 feet per yard).
4x8x16, solid light weight (you can find at Lowe's and HD) - 27 lbs when dry, 28 lbs when wet

About 0.35 pounds.
To calculate the cubic yards of concrete needed for a slab measuring 12 feet by 28 feet by 4 inches, first convert the dimensions to feet. The volume in cubic feet is 12 × 28 × (4/12) = 112 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 112 by 27. Thus, you need approximately 4.15 cubic yards of concrete.
1 mile = 1760 yards so 28 miles = 49 280 yards.
28 meters = 30.621 yards
