    That is what I got. I might have done something wrong.

    It's counting it wrong saying to cube the cm to m conversion so the units will cancel. Any idea what I could be doing wrong there?

    I multiplied the 19.3 by .10

    It's saying "You forgot to cube the cm to m conversion factor to makes the units cancel properly", it's an online site called Connect. It lets you got and check your answers.

    That's what I'm thinking but it is refusing to take the answer.

    Do you have any idea what I'm doing wrong with this problem?

    bro. Gold is a lot heavier than 1.93 kilos per cubic meter

    19.3 g/cm^3 * 1kg/1000g*(100cm/1m)^3

    100 cm^3 != 1m^3 (100)^3 cm^3 = 1 m^3

    a cubic meter of gold is going to be 19300 kilograms.

    metals are heavy, and gold is EXTREMELY heavy.

    and by heavy I mean dense...

    So it would be 19,300

    it makes no sense for a cubic meter of gold to weigh 1.93 kg... you should always check your answers. 1.93 kg is around 4.25 pounds. a cubic meter is a box 3 feet by 3 feet by 3 feet. Do you really think a solid metal box 3 feet by 3 feet by 3 feet would weigh only 4.25 pounds?

    the answer is no, it will weigh much more than 4.25 *tons* if it is gold

    the number you came up with, fyi, is approximately the density of certain *gases*

    air has a density of around 1.2kg/m^3

    Comparing the weights makes it make more sense.
