Answer:
Cork: Less
Wood: About the same
Metal: More dense
Step-by-step explanation:
Whether or not a block floats inside water is dependent on its density. If it is floating, it means it has a lower density. If it is sinking, it means it has a higher density. If it has the same, it will be half under and half over.
Mathematically, specific gravity can be used to support this phenomenon.
*In this context, water is our reference and the blocks are our substances.
Since Boyancy force can be described 
(the weight of the fluid disperced), having a higher density p than the reference liquid inherently will cause a greater downwards force from gravity.
F(-3)=(-3)2 - 1 / -3 + 4
f(-3)= -6 -1 / -3 + 4
f(-3)= -7/1
f(-3)=-7
Answer:
No
