    Answer 1) The density of the cube will be 17.30 g/mL

    We know the edge that is 1 inch, we have to convert it into cc which will be;

    1" = 16.38 cc and cc = mL

    The given mass is in oz, we need to convert this as well in g;

    10 oz = 283.495 g;

    We have the formula as Mass = Density / Volume

    Substituting the values; Density = (283.495 / 16.38) = 17.30 g/mL

    So the density will be 17.30 g/mL

    Answer 2) The density of cube will be 1.738 Kg/L

    The same procedure of conversion would be done here,

    Mass in Kg will be 0.02834 Kg and Volume will be 0.0163 L

    On solving with the equation as Mass = Density / Volume;

    Density = (0.02834 / 0.0163) = 1.738 Kg/L

    Hence, the density will be 1.738 Kg/L
