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
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).
The term "yards" of concrete means cubic yards.
How thick? Gotta have thickness to calculate cubic yards.
39.1116 cubic yards
123.44 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)
It depends on the thickness. The formula is: square feet × (thickness in inches ÷ 12) ÷ 27 = cubic yards So for 900 sq ft: • At 4" thick: 900 × 0.333 ÷ 27 = 11.11 cubic yards (order ~12.2 with 10% waste) • At 6" thick: 900 × 0.5 ÷ 27 = 16.67 cubic yards (order ~18.3 with 10% waste) Always add 10% extra — subgrade is never perfectly level and forms deflect a bit. Coming up short mid-pour is way worse than having a little left over. This slab calculator does the math for you: concretecalcus[dot]com/slab/24x24/
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
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.
