the density of a diamond is 3.52 grams per cubic centimeter. Sally has a diamond that has a volume of 20 mm^3. What is the weight of the diamond?.

  • math - ,

    m=mass[gr]

    V=Volume[cm^3]

    rho=densty[gr/cm^3]

    1cm=10mm

    1mm=1/10 cm

    1mm^3=(1/10)^3=1/1000=0.001cm^3

    V=20*0.001=0.02 cm^3

    m=V*rho=0.02*3.52=0.0704 gr


    P.S.
    rho is small Greek letter rho
