Find the buoyancy force acting on the octopus, if the volume is 0.2 m³.

V = 0.2 m ^ 3.
g = 9.8 m / s ^ 2.
ρ = 1025 kg / m ^ 3.
Farkh -?
The buoyant force or the Archimedes force is determined by the formula: Farch = ρ * g * V. Where ρ is the density of the fluid in which the body is immersed, g is the acceleration of gravity, V is the volume of the body immersed in the fluid.
Farch = 1025 kg / m ^ 3 * 9.8 m / s ^ 2 * 0.2 m ^ 3 = 2009 N.
Answer: the buoyancy force Farch = 2009 N. acts on the octopus.
