300 g of fluid A, whose density is 720 kg.m-3, is mixed with two other fluids, B and C, whose specific gravities are 0.9 and 1.1, respectively. The volumes of these two fluids are VB = 300 ml and VC = 170 ml. When a cube, edge length = 5 cm, is immersed in the fluid mixture, 75% of its volume becomes submerged. What is the density of the cube?
