Question

Ada sebuah kubus dngn rusuk 5 cmvdan massa nya 0,625 kg hitunglah massa jenis kubus tersebut?

Answer 1

Volume rusuk = s³ = 5³ = 125 cm³ 
massa = 0,625 kg = 625 g
ρ = m / v = 625 / 125 = 5 g/cm³

Answer 2

Diketahui :
R = 5 cm
m = 0,625 kg

ditanyakan;
ρ = ?

jawab :
ρ = m/V
ρ = m /R³
ρ = 0,625/ 5 ³
ρ = 0,005 kg/cm³ = 5 kg/m³
