The video tutorial explains the concept of buoyant force and its calculation using the formula FB = ρgV, where ρ is the density of the liquid, g is gravity, and V is the volume of the object. The tutorial covers different methods to calculate the volume of an object, including using cross-sectional area and height, density and mass, and length, width, and height. It also provides tips for exam preparation related to buoyant force calculations.
