  • 水的密度是1000kg/m3.一个2*4*3m3的水缸里装满了水.水的体积是多少?水的质量是多少?水对缸底的压力是多少?缸底的面积是多少?压强是多少?

    answer:1.the volume of water is :v=2*4*3=24m3.

    2.The mass of the water is=1000*24=24000kg

    3.the force the water exerts on the bottom is F=mg=24000*10=240000N

    4.the area of the aquarium is 2*4=8m2

    5.the pressure is:240000/8=30000N/m2
