Finding the buoyancy force and net force?

Mammalian brains are surrounded by cerebrospinal fluid. For a chimp, the brain volume is about 400cm3, and the average density if 1040kg/m3. The cerebrospinal fluid has an average density of 1007kg/m3. Find the buoyancy force and the net force.

I have tried using and manipulating the buoyancy force = rho x volume x g equation but am seemingly unable to get the correct answer.

Thanks in advance.
