The density of aluminum is 2.7 * 10 cubic kg / cm3, the mass is 270g, and the volume is 270cm3_____________ Floating and sinking?

G=mg=270*10^(-3)*10=2.7（N）
If immersed, then
F floating = ρ water GV drainage = 1.0 * 10 ^ 3 * 10 * 270 * 10 ^ (- 6) = 2.7 (n)
So when immersed in water, f = G
Therefore: suspension
