For a constant hydraulic stress on an object, the fractional change in the object's volume $$(\Delta V / V)$$ and its bulk modulus $$B$$ are related as

For a constant hydraulic stress on an object, the fractional change in the object's volume $$\left( {{{\Delta V} \over V}} \right)$$ and its bulk modulus B are related as

If a man becomes a giant, expanding his linear dimensions by a factor of eight, and assuming his density remains unchanged, the factor by which the stress in his legs will increase is
