# A raft of density \( 0.7 \rho_{w} \) floats partially submerged in a body of water of density \( \rho_{w} \). The raft has dimensions of length \( L \), width \( W \), and height \( H \), as shown in the figure. The height of the raft beneath the surface of the water is \( h \). Which of the following expressions is equal to \( h \)?

A raft of density \( 0.7 \rho_{w} \) floats partially submerged in a body of water of density \( \rho_{w} \).
