Please be clear with your solution and write an explanation for every formula and solution. Problem:Laguna Lake has a surface area of 708,800 sq.m. Based on collected data, Pasig river flows into the lake at an average rate of 1.5 cu.m/s and the Paranaque river flows out of the Laguna lake at an average rate of 1.25 cu.m/s during the month of June. The evaporation rate was measured as 19.4 cm/month. Evapotranspiration can be ignored because there are few water plants on the shore of the lake. A total of 9.1 cm of precipitation fell this month. Seepage is negligible. Due to the dense forest and the gentle slope of the land surrounding the lake, runoff is also negligible. The average depth in the lake on June 1 was 19 m. What was the average depth of June 30?
