If 180 bags of cement are to be transported to a construction site every day, it will take 40 days. Now it will take 25 days to complete the transportation, how many bags should be transported every day?

X bags should be delivered every day
180：X=25：40
25X=180*40
25X=7200
X=7200/25
X=288
288 bags a day

How to calculate the sectional area of triaxial cement mixing pile? The diameter of pile is 850,

I don't know if your 850 & 600 ones need to be nested. The cross-sectional areas of large, small and medium ranges are different
