AP Physics 1· difficulty 1/5

A block of aluminum has mass 540 g540~\text{g} and volume 200 cm3200~\text{cm}^3. What is its density?

  • A

    1.4 g/cm31.4~\text{g/cm}^3

  • B

    5.4 g/cm35.4~\text{g/cm}^3

  • C

    2.7 g/cm32.7~\text{g/cm}^3

    check_circle
  • D

    27 g/cm327~\text{g/cm}^3

Explanation

ρ=m/V=540/200=2.7 g/cm3\rho = m/V = 540/200 = 2.7~\text{g/cm}^3 (matches aluminum).
