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.
Depends on the length of the hole.

112 cuft
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.")
.99 yds
That hole is 6 feet deep or 72 inches deep.
About 21 cubic feet
2 inches = 1/6 foot27 cubic feet = 1 cubic yardVolume of the hole = (15' x 7' x 1/6-ft) = 17.5 cubic feet = 0.648 cubic yard (rounded)
A hole with two dimensions has no third dimension. → its volume is 6 ft × 10 in × 0 ft = 0 ft³ → You require NO concrete to fill a hole which is given as an area as it has NO volume.
