Let the volume of the empty flowerpot be V-pot (cm3) and the mass of the empty flowerpot be m(g). When an empty flowerpot is filled with water, the volume of water is V-pot, and the flowerpot filled with water is weighed as m? (g), then what is the mass of water poured into the empty flowerpot? -m(g) is known from the formula: m=ρV, and ρ water = 1(g/cm3), then:

V basin =V water =m water/ρ water =(m? -cubic meters)
