Determine the volume of a copper cube, which, when immersed in kerosene, is pushed out with a force of 1.6 N

It is obvious that the cube is pushed out by the Archimedes force (1.6 N). Its formula is F = pgV, where p is the density of the liquid (800 kg / m3 for kerosene), g is the acceleration of gravity (g = 9.8 m / s2), V is the volume of the displaced liquid and the volume of the body.
Let us express the required value: V = F / pg. Substitute the numbers: V = 1.6 / (800 * 9.8) = 0.000204 m3 = 204 cm3
