Solid cube wood block with side length of 10cm, density of 0.6 × 10 ｛ kg / m ｛ 179;; is still in a container with enough water, and its upper and lower bottom surfaces are smooth Parallel to the water surface, (the wood block is not completely immersed in water) calculation: 2.

Buoyancy is gravity, that is, f = g = mg = 0.1x0.1x0.6x10 ^ 3x10 = 6N
Volume f = ρ VG, v = f / ρ g = 6 / 1000 / 10 = 6x10 ^ (- 4) m ^ 3
Pressure, P = ρ GH, where h = V / S = 6 / 10000 / 0.1 / 0.1 = 0.06m, then p = 1000 * 0.06 * 10 = 600Pa
