Problem

A solid cube floats in water such that exactly three-fourths of its volume is submerged. Which option best represents the ratio of the density of the cube (ρc)(\rho_c) to the density of water (ρw)(\rho_w)? (a) ρc=1.33 ρw\rho_c = 1.33\,\rho_w (b) ρc=1.00 ρw\rho_c = 1.00\,\rho_w (c) ρc=0.75 ρw\rho_c = 0.75\,\rho_w (d) ρc=0.25 ρw\rho_c = 0.25\,\rho_w
