help please bang besok di kumpulin tolong di jawab cepat
Penjelasan:
V = 27.000 L
p = 1 g/cm³ = 1000 kg/m³
h = 120 cm = 1,2 m
...
Sisi kubus :
V = s³
27.000 = s³
s = 30 L atau 30 dm
s = 3 m
...
Besar tekanan hidrostatis :
Ph = p . g . h
Ph = 1000 . 10 . (3 – 1,2)
Ph = 1000 . 10 . 1,8
Ph = 18.000 N/m²
