    density = 8.87g/cm³

    From chart the density shows that it is a Colsibro copper alloy, a precipitation hardening copper nickel silicon.

    Step-by-step explanation:

    This problem bothers on the density of substances

    Given data

    Mass m of substance = 239.6grams

    length l=3cm

    width b=3cm

    height h=3cm

    Volume of substance = l*b*h

    =3*3*3=27cm³

    We know that the density of the substance ρ=mass/volume

    ρ = 239.6/27 = 8.87g/cm³
