I need to know the following:What is the volume of a bar of copper?What is the volume of an object made of lead?What is the mass of a bar of gold?Would be great if you could help.
we need to know more information than that. A bar of copper could be any sized bar. The mass of a bar of gold is dependent on its volume. What are the dimensions of the lead object?
These are all density problems (you answered the one about lead) Copper has a density of 8.94 gr/cc Gold has a density of 19.30 gr/cc So for copper, 250 g / 8.94 g/cc 27.96 cc For the gold, 19.30 x 8 x 60 x 5.25 48,636 g or 48.636kg Grandpa
