The buoyant force is calculated using the formula: Buoyant Force = Volume × Density of fluid × g. Here, the volume is 6 × 10^-3 m³, the density of air (fluid) is 1.3 kg/m³, and g (acceleration due to gravity) is approximately 9.8 m/s². Thus, the buoyant force is 6 × 10^-3 m³ × 1.3 kg/m³ × 9.8 m/s² = 0.07644 N, which is approximately 0.08 N.
