    The sample of lead has a volume of 11.1 cm³

    Explanation:

    Step 1: Data given

    x cm³ lead has a density of 11.3 g/cm³

    it has the same mass as 330cm³ of a piece of redwood with density 0.38g/cm³

    Step 2: Calculate mass of the piece of redwood

    Density = mass/volume

    mass = density * volume

    Mass of the piece of redwood = 0.38 g/cm³ * 330cm³ = 125.4 grams

    Since the sample of lead has the same mass, it also has a mass of 125.4 grams

    Step 3: Calculate volume of the lead

    Density = mass / volume

    Volume = mass / density

    Volume of lead = 125.4g / 11.3g/cm³ = 11.097 cm³≈11.1 cm³

    The sample of lead has a volume of 11.1 cm³
