How to calculate buoyancy
Find the volume of the submerged portion of the object.
The force of buoyancy that acts on an object is directly proportional to the volume of the object that is submerged. In other words, the more of a solid object that is submerged, the greater the force of buoyancy that acts on it.

Options:
(i) Buoyancy differs based on the object that is submerged. The volume of a submerged object, according to mass, is higher than that of a solid solid in terms of mass..
(ii) Think about how much the object weighed when submerged. If you are using a dishwasher, the weight should be not taken into account when calculating buoyancy..
(iii) The mass of the object you are assessing will vary widely. Both forms of buoyancy act in the same way..
(iv) This means that even objects that sink in liquid have a buoyancy force pushing upwards on them. To begin to calculate the buoyancy force acting on an object, your first step should generally be to determine the volume of the object that is submerged in fluid..
(iv)
