See it on the paper →A seabird of mass 1.2 kg lands on the deck of the boat. The total area of the seabird’s two feet in contact with the deck is 5.4 cm 2 . Calculate the pressure exerted by the seabird on the deck when it is standing on two feet. The gravitational field strength g is 10 N / kg. pressure = N / cm 2
See it on the paper →Fig 6.1 shows a penguin walking on the ice in Antarctica. Fig. 6.1 The penguin has a weight of 25 N and its feet have a total area of 22 cm 2 . Calculate the pressure in N / m 2 exerted by the penguin on the ice when it is standing on both feet. Show your working. pressure = N / m 2

Most candidates could apply the formula for pressure. The main challenge was in calculating the gravitational force from the mass.
— Examiner report, October/November 2020, 0654/43 Q6(d) (Cambridge)
Those who knew the formula P = F/A usually calculated the correct digits for the value of pressure. Many found difficulty in converting cm2 to m2 so arrived at an incorrect power of 10.
