An aluminum block has a mass of 0.25 kg and a density of 2700 kg/m3. a) Calculate the volume of the aluminium block. b) Determine the buoyant force exerted on this block when it is completely submerged in water of density 1000 kg/m3

a

The volume of the aluminum is  

b

The buoyant force exerted is  

From the question we are told that

                  The mass of the aluminum is

                   The density of the aluminum is

Generally volume is mathematically represented as

 Substituting values accordingly

Generally buoyant force is mathematically represented as

Where  V is the volume of the aluminum

            is the density of water

           g  is the acceleration due to gravity =

Substituting these values accordingly we have
