There can be no equivalence.
A cubic yard is a measure of volume in 3-dimensional space while a square foot is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
For a 4-inch thick slab, you will need at least 9.48 Cubic Yards.
multiply the number of square yards - which is an area - by the average height in yards to get the volume in cubic yards
A yard of concrete is 27 cubic ft. Your measurements, if in feet, represents 480 cubic ft. Dividing this by 27 results in 17.78 yards.
8.25 cubic yards of concrete
7 feet by 14 feet = 98 square feet 98 square feet by 4 feet = 392 cubic feet There are 9 square feet in a square yard, and there are 29 cubic feet in a cubic yard.... so 392 cubic feet = 14.519 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.
40.1 cubic yards
The term "yards" of concrete means cubic yards.
You cannot "fill" a cubic measurement with a square measurement.I think you meant cubic yards.1 cubic yard = 27 cubic feet.Your concrete slab is 1600 x 4/12 cubic feet = 533.333333... cubic feet.533.333333... cubic feet / 27 = 19.753 cubic yards (rounded to third decimal).
How thick? Gotta have thickness to calculate cubic yards.
123.44 cubic yards
39.1116 cubic yards
1 cubic yard = 27 cubic feet700 square feet x 1/2 foot = 350 cubic feet = 1226/27 cubic yards(12.963 cubic yards, rounded)
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
To calculate the amount of concrete needed for a 900 square foot area, you first need to determine the thickness of the concrete slab. Once you have the thickness in inches, divide it by 36 to convert to yards. Then divide the total cubic yards by the number of cubic yards in a concrete truck to determine how many truckloads you need.
At a poured depth of 4 inches, you will need 4.94 cubic yards.
Concrete in the bulk is measured in cubic yards. Concrete on the ground is often measured by square yards, but the depth of the concrete must be known, too. The price per cubic yard varies a lot across the US, plus not knowing the thickness of the concrete means that your question cannot reasonably be answered.
