Problem

A wooden block floats in water with one–fourth of its volume above the surface. Which statement about the density of the wood compared to the density of water is correct? (a) ρwood=ρwater\rho_{\text{wood}} = \rho_{\text{water}} (b) ρwood<12 ρwater\rho_{\text{wood}} < \dfrac{1}{2}\,\rho_{\text{water}} (c) 12 ρwater<ρwood<ρwater\dfrac{1}{2}\,\rho_{\text{water}} < \rho_{\text{wood}} < \rho_{\text{water}} (d) ρwood>ρwater\rho_{\text{wood}} > \rho_{\text{water}}
