A rectangular agricultural plot measures 20 meters in length and 14 meters in width. A pit measuring 6 meters long, 3 meters wide, and 2.5 meters deep is excavated at one corner of the plot. The soil removed from the pit is evenly spread over the remaining area of the field. By how much has the level of the field increased?

Explanation

The volume of earth dug out from the pit is calculated by multiplying its length, width, and depth (6 m × 3 m × 2.5 m). This soil is then spread evenly over the rest of the field, whose area is the total field area minus the pit area ((20 m × 14 m) - (6 m × 3 m)). The increase in the field's level is found by dividing the volume of soil by the remaining area, resulting in a rise of 17.18 centimeters.
