Initial data: V (ball volume) = 20 m3.

Reference values: ρw (average air density at 20 ºС) = 1.204 kg / m3; g (acceleration due to gravity) = 10 m / s2.

The buoyancy force (Archimedes force), which acts on a given ball, can be calculated by the formula: Fа = ρw * g * V.

Let’s perform the calculation: Fа = 1.204 * 10 * 20 = 240.8 N.

Answer: A buoyant force of 240.8 N. acts on this ball.
