Tolong dibantu yaa pakai jalan itu gambarnya mksh. ....

FLUIDA STATIS

ₓ = benda, ₐ = air, ₘ = minyak

wₓ = wₐ + wₘ
ρₓ g Vₓ = ρₐ g Vₐ + ρₘ g Vₘ
ρₓ hₓ = ρₐ hₐ + ρₘ hₘ
ρₓ = (ρₐ hₐ + ρₘ hₘ) / hₓ

ρₐ = 1000 kg/m³. hₐ = 4 cm
ρₘ = 800 kg/m³. hₘ = 10-4 = 6 cm
hₓ = 10 cm

Massa jenis benda
ρₓ = (ρₐ hₐ + ρₘ hₘ) / hₓ
ρₓ = (1000 • 4 + 800 • 6) / 10
ρₓ = 880 kg/m³

Berat jenis benda
sₓ = ρₓ g
sₓ = 880 • 10
sₓ = 8800 N/m³. ✓
