There is no way to calculate cost for a square foot of concrete (?" w x ?" l). In order to calculate cost you need to first calculate volume which requires a third dimension of height (?" w x ?" l x ?" h). Concrete is usually sold by the cubic yard (36" wide x 36" long x 36" high). Another factor in calculating price of concrete is distance to delivery location.
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).
25 Yards of concrete
Not square yards, but Approx. 5.24 cubic yards 54'2" = 650" x 7'10" = 94" x 4" = 4" = 244,400 cubic inches / 46,656 cubic inches = 1 cubic yard (36" x 36" x 36")= 5.24 cubic yards
Concrete never fully cures, but a non-quicksetting concrete should be firm on the surface in about 4-8 hours, and usable for foot traffic or post setting in 36 hours.
For a hole 36" deep X 18" diameter, you would need approx. 1/5 cu. yd. concrete.
Depends on the length of the hole.
If the post is a 6 x 6 you will need about 1/10 of a yardof concrete
I use one bag to 1 1/2 bags per hole and fill the rest of the way back with tamped topsoil... whatever came out of the hole.
That depends on how deep (thick) you need it to be. You'll need 1 yard of concrete for every 3/4 inch of thickness of the pad.
The electrical is down at 36". It should not affect your driveway.
Based on your dimensions and a standard 3.5" to 4" thickness you will need 7 yards of concrete.
To fix a washing line clothes post, you typically need about 2 to 3 bags of concrete, depending on the size of the post and the depth of the hole. A standard hole for a clothes post is usually around 12 inches in diameter and 24 to 36 inches deep. It's important to ensure the post is securely anchored in concrete to withstand wind and weight from hanging clothes. Always check the manufacturer's recommendations for specific guidance based on the post's size and material.
If the hole is a square then there is 36 cubic feet of dirt in the hole.

To calculate the amount of concrete needed for a slab measuring 36 feet by 10 feet with a thickness of 4 inches, first convert the thickness to feet (4 inches = 1/3 feet). Then, calculate the volume: (36 \times 10 \times \frac{1}{3} = 120) cubic feet. Therefore, you will need 120 cubic feet of concrete for the project.
