42 cubic feet or 1.56 yards.
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.
1.042 CF of concrete per unit
3.16 Cubic Yards
about 17 yards of concrete (it's sold by the cubic yard)
A standard 8x8x16 2 core block contains about .25cf of open space
18.6240 yd³
about 432 cubic inches
Depends on the length of the hole.
How much concrete is required to fill 100 cu feet
You need to specify how deep the area is to answer the question; this is a volume problem. Please ask again

How deep do you want the concrete to be?
To calculate the amount of concrete needed to fill a 12-inch diameter hole that is 18 inches deep, first convert the measurements to feet: the diameter is 1 foot and the depth is 1.5 feet. The volume of a cylinder is given by the formula V = πr²h. The radius (r) is 0.5 feet, so the volume is approximately π(0.5)²(1.5) = about 1.18 cubic feet. Thus, you would need roughly 1.18 cubic feet of concrete to fill the hole.
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.
