    Answer:

    weight= 1805.04 N

    Explanation:

    In this problem we are expected to find the weight of the plastic tank and the weight of the equal volume of water

    Given that

    density of water = 1000 kg/m^3

    volume of plastic tank is same as the volume of water= 0.18 m^3

     

    we need to solve for the mass of the water

    we know that density is = mass/volume

    1000= mass/0.18

    mass= 1000*0.18

    mass= 180 kg

    the total mass of the combined system is

    4+180= 184 kg

    the weight = mg (assuming g= 9.81 m/s^2)

    weight = 184*9.81

    weight= 1805.04 N
