Question

Jika massa benda sebuah kubus besarnya 10 kg dan ukuran rusuknya 10 cm,maka besar massa jenis kubus tsb adalah.......(kg/m3) tolong dijawaby tks:D

Answer 1

M = 10 kg
r = 10 cm = 10⁻¹ m
V = r³ = (10⁻¹)³ = 10⁻³ m³
ρ = ?
ρ = m /V
ρ = 10 / 10⁻³ = 10.000 kg/m³

Answer 2

Dik :
V = r³ = (10⁻¹)³ = 10⁻³ m³
m = 10 kg
r = 10 cm = 10⁻¹ m

Dit :
ρ....?

Dij ;
ρ =
ρ = 10 / 10⁻³
ρ = 10.000 kg/m³

Semoga membantu
