To calculate the volume of concrete needed for a footer that is 12 inches wide and 3 feet deep, first convert the dimensions to feet. The width is 1 foot (12 inches) and the depth is already 3 feet. The volume is calculated using the formula: volume = width × length × depth. Assuming the length is 1 foot, the volume would be 1 ft × 1 ft × 3 ft = 3 cubic feet of concrete needed.

To calculate the volume of concrete needed for footings that are 28 feet long, 2 feet wide, and 3 feet deep, use the formula for volume: length × width × depth. This results in a volume of 28 ft × 2 ft × 3 ft = 168 cubic feet. Therefore, you will need 168 cubic feet of concrete for the footings.

The depth and width of a footer for a concrete pad will depend on various factors such as the load that will be placed on the pad, soil conditions, and local building codes. Generally, footers are often at least 12 inches deep and extend beyond the pad on each side by at least 6 inches. It is recommended to consult a structural engineer or local building authority for specific requirements for your project.
1.24 cubic yards.
Depends on the length of the hole.
You'll need 3.53 cubic yards of cement.
you would need 37.33 yards of concrete or 38 to be safe
you will need about 4 cuyds for your project.
Depends how wide the 3 yard length is and how deep the concrete is put over that area.
