The buoyant force is stronger than the gravity force (the block's weight). Consequently, the block's density is smaller than water's density.
Explanation:
Archimedes principle affirms that a body submerged in a fluid (for example a liquid, or more precisely, water) experiences an upward force equal to the weight of fluid (liquid, water) displaced.
Mathematically,
buoyant force
while the weight
As the body floats
