Answer:
Step-by-step explanation:
Object is Floating in a liquid
weight of object is equal to weight of displaced fluid
i.e.
![\rho _oVg=\rho _mV'g](https://img.qammunity.org/2020/formulas/physics/high-school/nylyaqv1fguc7pigr8szifxci5lx30p4kv.png)
i.e.
![\rho _oV=mass\ of\ object](https://img.qammunity.org/2020/formulas/physics/high-school/yat0dwyw4y1xjx514jc5b8haf8cl01dt6m.png)
where V and V' is the volume of object and volume of object inside the liquid.
therefore mass of liquid displaced must be equal to mass of object
