A soil excavation project can be completed in 16 days if A alone does it, but it takes 20 days for team B to do it alone. Now the two teams are working at the same time, and the work efficiency is increased by 20%. When the project was completed (1/4), the groundwater suddenly encountered, which affected the construction progress and reduced the excavation of 47.25 square meters of soil per day. As a result, it took 10 days to complete the project. How much square soil should be excavated for the whole project?
一项挖土工程，如果甲单独做，16天可以完成，乙队单独做要20天才能完成，现在两队同时施工，工作效率提高20%．当工程完成(1/4)时，突然遇到地下水，影响施工进度，使得每天少挖土47.25方土，结果共用了10天完成工程，整个工程要挖多少方土？
