621 ft looks wrong... its 207 ft
An re test question gave the answer as:
We know the total square yardage as well as the frontage expressed in feet. Since area is a function of length times width, and since there are 9 square feet in each square yard, we know that 40 times X divided by 9 will give us our answer. To make the calculation, multiplying 920 yards by 9 will allow us to divide the result by 40 to find the depth, which is 207 feet.
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
depends on the depth that you need to cover the 1200 square feet (area) to. there are 3 foot to 1 yard (1 foot=3 yards). so 1 square foot = 9 square yards (3x3). 1200 square feet = 1200 x9 = 10,800 square yards. you then multiply the 10,800 by the amount of yards (depth) that you want to cover the area to.
720 square feet at the standard 4-inch depth requires 8.9 cubic yards.
For a 4-inch depth you need at least 14.81 cubic yards.
1000 square feet/9 = 111.1 square yards of concrete 6 inches thick. This is the same as 111.1/4.5 = 24.7 cubic yards of concrete.
8000 sq yds is 8000x9 = 72000 sq ft. If frontage is 590 feet, then the depth is 72000/590 = 122 feet
920 sq yards with 40-foot frontage
56.33 square yards.
Cannot answer the question with out the depth dimension. If you are talking about square yards then 20x5 = 100 square feet, divided by 9 = 11.11 square yards,
77/9 cubic yards for every inch of depth.
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.

you cannot do that; square yards is two dimensios, not three. You would need to know height to get cubic yards

For a 4-inch depth you need at least 14.81 cubic yards.
25 Yards
At a poured depth of 4 inches, you will need 4.94 cubic yards.
