density of water displaced volume gravitational pull on Earth density of the aluminum cube
I gave my students this multiple choice question: A small aluminum cube is dropped into a beaker of water to determine the buoyancy. Which of these is not necessary in determining the buoyant force acting on the cube?

Only one answer is correct among these 4 choices:
- density of water
- displaced volume
- gravitational pull on Earth
- density of the aluminum cube

Could you tell me which one is correct?

density of the aluminum cube
