The pressure at a depth h in a fluid is given by P = ρgh, where ρ is the density of the fluid and g is the acceleration due to gravity. In this case, the pressure is 1.0 × 10⁵ N/m², the density of air is 1.29 kg/m³, and the acceleration due to gravity is 9.8 m/s². Solving for h, we get h = P/ρg = (1.0 × 10⁵ N/m²)/(1.29 kg/m³)(9.8 m/s²) = 7900 m.
