If the height of a cylindrical bucket is changed to twice the original height and the bottom diameter is changed to half the original diameter, it can hold 40 kg of water, then the original bucket can hold water______ Kilogram

If the height of a cylindrical bucket is changed to twice the original height and the bottom diameter is changed to half the original diameter, it can hold 40 kg of water, then the original bucket can hold water______ Kilogram

If the original height of the bucket is h, then the current height of the bucket is 2H. If the original bottom radius of the bucket is 2R, then the current bottom radius of the bucket is r, then the current volume of the bucket: the original volume of the bucket = (π R2 × 2H): π (2R) 2H = 2:4 = 1:2, so the current volume is the original 12,40 △ 12 = 80 (kg). Answer: the original bucket can hold 80 kg of water ．
