To fill air holes in concrete, first clean the area around the hole to remove any loose debris or dust. Then, use a concrete patching compound or a mix of cement and water to fill the hole, ensuring it's packed tightly. Smooth the surface with a trowel and allow it to cure according to the manufacturer's instructions. For small holes, a concrete repair caulk can also be effective.
Yes you can. There is a special concrete formula made by sackrete that you just add water to the concrete after pouring it in a hole.
3 yards. 1 yard is a cubic (not square) yard and is 36 inches on all three sides. The calculation looks like this: (216x216x3)/(36x36x36)=3.0
10 bags. Each 80 lb bag is 0.6 cubic feet, and your hole is 6 cubic feet.
40x68x36=97,920 in.^3 1728in.^3 per 1ft^3 in volume 97920/1728=56.7 ft^3 of concrete in volume 27ft^3 per 1 Yd^3 in volume 56.7/27=2.1 yd^3 of concrete to fill the hole You can not order exactly 2.1 yards of concrete though. I think they only go up by half yard increments.

None, as a hole which is 6 inches wide and 42 inches long has no depth and thus no volume.
To install a mailbox post correctly, dig a hole at least 24 inches deep, place the post in the hole, and fill it with concrete. Make sure the post is level and allow the concrete to set before attaching the mailbox.
Depends on the length of the hole.
To effectively fill a deep hole in a concrete floor, you can follow these steps: Clean the hole thoroughly to remove any debris or loose material. Use a concrete patching compound to fill the hole, following the manufacturer's instructions. Apply the patching compound in layers, allowing each layer to dry before adding the next. Smooth out the surface of the patch to match the surrounding concrete floor. Allow the patch to cure completely before walking or placing heavy objects on it.
The recommended method for installing a concrete footing for a 6x6 post is to dig a hole that is at least 12 inches in diameter and 24 inches deep. Place a cardboard tube form in the hole and fill it with concrete, making sure it is level. Insert a post anchor into the wet concrete and allow it to cure for at least 24 hours before attaching the post.

To install a Saskatoon (saska) pole for basketball, dig a hole 3 feet deep and roughly 18 inches in diameter, set the pole in the hole, and fill it with concrete. Ensure the pole is level and allow the concrete to cure for at least 24 hours before mounting the backboard and hoop.

25 feet is equal to 300 inches. The radius of a hole is half its diameter, which equals 4 inches. The volume of the cylinder is given by the formula v = [Pi]r2h, so the volume of your hole is 3.14 * 16 * 300 = 15080 cubic inches. There are 1728 cubic inches to the cubic foot, so you'll need about 8.75 cubic feet of concrete, which is about a third of a yard. (More exactly, that's a cubic yard, but concrete guys just say "yard.")
