Five solid objects made of different materials are placed in a tub of water. The objects are cubes made of wood, ice, aluminum, steel and gold.
All of the objects have the SAME mass. The objects are released and allowed to reach some equilibrium position. Note that some of the objects will float, while others will sink.
Which of the following statements are true? (Give ALL correct answers)

A) The wood cube would displace its own volume in water
B) The aluminum cube would feel the least buoyant force
C) The wood cube and the ice cube would both feel the greatest buoyant force
D) The ice cube would float
E) The wood cube and the ice cube would displace the most water

#### Solution Preview

A) The wood cube would displace its own volume in water
FALSE
Density of wood is less than that of water. It needs to displace lesser volume of water than its own volume to float.

B) The aluminum cube would feel the least ...
