The formula you are going to use for this question is the density formula, which states that: D = M/V, Where D = density = 11.34 g/cm3 M = mass of lead = 408g V = volume of water displaced = ? D = M/V Make V the subject of the formula V = M/D = 408/11.34 = 35.98 V = 35.98 ml. Thus, 35.98 ml of water will be displaced by the lead.
