Tóm tắt:                                                                    Giài:

m = 60 kg

S = 30 cm^2

p =?

                                                    30 cm^2 = 0.003 m^2

                                              Diện tích của hai bàn chân thầy Hùng là:

                                           0.003 . 2 = 0.006 ( m^2)

          Vì thầy đứng trên mặt sàn nằm ngang nên áp suất mà thầy tác dụng lên mặt sàn chính là trọng lượng thầy nên:

p = F/s = P/s = 10m/0.006 = 100 000(Pa)

2/5 km^2 =  0.4 km^2 = 400 000 m^2

Ghi nhớ: 1 km^2  = 1 000 000 m^2
