Calculate the magnitude of buoyant force
Consider two cubes: a copper cube (Density = 8.96 g/cm3 and a lead cube (Density = 11.4 g/cm3 that both have an edge length of 3.0 cm
Calculate the magnitude of the buoyant force (in Newtons) acting on the copper cube and the lead cube when each is fully submerged in water. Show your work.
Thanks in advance for any help!

Welcome to PF.
we know that the density of water is 1g/cm^3. Which means that we know both of these materials are much more dense than water.
Lets explore what buoyant force with respect to water is. The buoyant force is equal to the weight in water displaced by the object. Both of these objects are the same volume correct? so both of the objects displace the same amount of water, right? so their buoyant forces are...
