Depends on what depth you want to spread the gravel at. This answer depends on knowing the cubic capacity of 50 lbs. of gravel.
Approximately 155cm

Volume = 120/12= 10 cubic feet for each 1 inch of depth= 2 bags for each 1 inch of depth.
The coverage area of 5 cubic feet of pea gravel will depend on the thickness at which it is spread. To determine this, you will need to know the desired depth of the pea gravel. You can calculate the square footage coverage by dividing the volume of the gravel (5 cubic feet) by the desired depth in feet.
Can't answer unless we know the depth of the gravel and width of the area.
If you use a depth of 3 inches, that area will be about 16.2 cubic yards (around 20.785 tons) of gravel.

9.26 cubic yards for every inch of depth.
It depends on how thick you want the gravel to be. All dimensions will be in feet. (fractions) Width x length x depth divided by 27 equalls cu. yds.

None. You have only given an area and no depth. Without a depth, the volume is zero and thus the hole does not exist and no gravel will be needed. If you meant a round hole 12 ft by 14 ft it is still unclear as to the dimension of the hole: firstly which is the depth (the 14 ft is the most likely), but when speaking of a round hole would you mean the perimeter, the radius or diameter for the given measurement? They all lead to different volumes and hence difference amounts of gravel needed to fill the hole. Ans 3 - 12 x 14 is NOT round it is rectangular
Depends on the depth of the gravel also. If depth is "D" feet then volume required is 62 x D cubic feet. Since each bag has 5 cubic feet you would need (60 x D)/5 bags (round it up to next higher number (as most shops won't sell you fractions of a bag).

It depends on the depth you want the gravel to be and also how much you are charged per cubic yard. However, you will need a minimum of 2,565.5 cubic yards of gravel if you use a 4-inch depth to cover 1,800 square feet. This equates to roughly 28.5 tons of gravel.
