QUESTION 10 In order to swindle people into paying for a brick of gold without actually investing in a brick of gold, people have considered filling the centers of hollow gold bricks with lead to fool buyers into thinking that the entire brick s gold. It does not work: Lead is a dense substance, but its density is not as great as that of gold, 19.3 g/cm". What is the density of lead if a cube of lead has an edge length of 2.00 cm and a mass of 90.7 g? (number only, round to one number after the decimal point)
