The homogeneous cube wood block with side length of 10 cm is still on the water surface, and its lower surface is 8 cm (g = 10 N / kg) from the water surface?

First of all, floating: F floating = g wood
F floating = ρ liquid GV discharge
V row = V wood-v dew
F = 1000 * 10 * 0.08 * 0.1 * 0.1 = 8N
G = 8N
M wood = 0.8kg
ρ wood = 0.8 / 0.001 = 800 kg / m3
It can also be used directly
ρ substance: ρ liquid = V row: V substance
