Depends on how thick the concrete pad is. At 4 inches thick and allowing for a little waste and imprecise measurements, about 350 square feet.

The term "yards" of concrete means cubic yards.
.029 cubic yards of concrete weighs aproximately 93.96lbs
10.67 cubic yards. Adjusting for safety, you should order a minimum of 11.5 cubic yards.
1.8 Cubic yards of concrete is 48.6 cubic feet. Each 80lb bag of concrete is .6 cubic feet. Therefore, you would need 81 bags. Hope that helps. GEO
To calculate the amount of concrete needed for a 12' x 36' x 4' pad, first find the volume in cubic feet by multiplying the dimensions: 12 x 36 x 4 = 1,728 cubic feet. Since concrete is typically measured in cubic yards, convert cubic feet to cubic yards by dividing by 27 (1 cubic yard = 27 cubic feet). Therefore, you would need approximately 64 cubic yards of concrete for the pad (1,728 ÷ 27 = 64).

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/
39 cubic yards is 29.81 cubic meters.
