Respuesta :

Answer:

23936.5 N/m² or 23936.5 Pa

Explanation:

Unit conversion

  • inches to meters ⇒ × 0.0254
  • pounds to kilograms ⇒ × 0.45

Our dimensions

  • 9 inches ⇒ 0.229 m
  • 280 pounds ⇒ 127.01 kg

Solving

  • P = F/A
  • P = mg/A
  • P = 127.01 x 9.8 / 0.229 x 0.229
  • P = 1244.698 / 0.052
  • P = 23936.5 N/m² or 23936.5 Pa
