Penjelasan:
1.
F = 20 N
A = (50 x 20 = 1000 cm²) → 0,1 m²
P = F/A
P = 20/0,1
P = 200 Pa
2.
P1 = P2
F1/A1 = F2/A2
40/(0,2 x A2) = F2/A2
F2 = 40/0,2
F2 = 200 N
3.
a) p.benda = 600
p.air = 1000
karena
pb < pa
maka keadaan benda tersebut adalah mengapung
b)
Pa.V = Pb.Vb
1000.V = 600 x 300
V = 180000/1000
V = 180 m³
