simple.....
just find the volume of the object in m^3.......
the body displaces this much water...........
but the density of water is 1g/cm^3;
so the weight of water displaced is equal to the volume of the body.........
and the weight of water displaced is equal to the buoyant force.........
therefore the volume of water expressed in Newtons is the buoyant force.................

Bouyant force is equal to the volume of the fluid displaced times the density of the fluid divided by the local gravitational field.

EDIT: For pure genius: How do you express volume in Newtons?
You seem to be suffering from the usual confusion between 'weight','mass', and 'force'. They are three -totally- different things.

Bouyant force can be calculated in two ways (1) By finding the vol. of the displaced liquid. This vol. should be multiplied by the density of the liquid. (2) By finding the apparent loss of weight.
