Please explain step by step.. take g=9.81m/s^2 and density of water: 1000kg/m^3

Question 10 1 pts The schematic figure below shows a cuboid of dimensions L (length) by L (breadth) by 21 (height) floating upright in a liquid of uniform density p. The upper half of the cuboid has a uniform density of p1 and the lower half of the cuboid has a uniform density of p2 . K corresponds to the center of he cuboid's square base, whereas G, B and M represent the cuboid's center of gravity, the center of buoyancy and the metacenter, respectively. Note that for two general vertical points P and Q, PQ is positive (negative) if O lies above (below) P. Also note that the relative positions of G, B and M are not drawn to scale in the figure below. Determine the metacentric height GM if p = 1000 kg/m3, 01 = 0.8p, p2 = 0.7p and L = 0.8 m. GM = m. Hint: Please include a negative sign if your answer is negative. L .M P1 1 - B P P2
