A cube of wood, measuring 4 in. (10.16 cm) on a side, floats in fresh water with 1/2 in. (12.7 mm) extending above the surface of the water.

a) What is the specific weight of the wood (lb/cu.in) (N/cc)?

b) For stability, should O₁
(center of gravity of block) be above or below O₂
(center of gravity of displaced water)?
