I used a machine shovel with a size of $0\mathrm{.}8$ m to dig sandy soil in an amount of $4912$m and under ideal standard conditions, without delay and with a rotation angle of $75$ as the working conditions and work management were good $$The expected productivity of the shovel on the flaccid scale if it worked is the swelling coefficient $22\%`\_\_$ The number of days needed to complete the drilling in full, since I knew that the number of working hours per day is $8\_$

What is the appropriate size of the shovel to increase its expected productivity by the scale of the bank and make it by $202\mathrm{.}23$ if the shovel is used in the same conditions mentioned above
