The recommended 5 drill bit size for drilling holes in metal is 0.2055 inches in diameter.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*5 ~= 157.1 square inches / 144 square inches/square foot = 1.091 square feet We have 30 such holes so total volume = 30*1.091 = 32.73 square feet.
Round holes in the ground about 2 inches in diameter can be caused by a variety of factors, including animal activity, such as burrowing by rodents or insects like ants and beetles. They may also result from natural processes like erosion or the impact of raindrops on loose soil. Additionally, human activities, such as digging for planting or post holes, can create similar-sized holes. In some cases, the holes could be remnants of a plant's root system or caused by the decay of organic matter.
