Calculate the pressure exerted on the ground by a 20m high marble column.

Initial data: h (height of the marble column) = 20 m.

Reference values: g (acceleration due to gravity) ≈ 9.81 m / s2; ρm (tabular value of marble density) = 1000 kg / m3.

The pressure that the marble column will exert on the ground is calculated by the formula: P = Fт / S = m * g / S = ρm * V * g / S = ρm * S * h * g / S = ρm * h * g.

Let’s make the calculation: P = 2700 * 20 * 10 = 540,000 Pa (540 kPa).

Answer: A marble column exerts a pressure of 540 kPa on the ground.
