Chemistry HELP!!

Can you identify a metal if you know its density? Explain

Do you think that determining the volumes of metal samples by measuring their dimensions and calculating would be more r less accurate than determining volumes by water displacement? Explain. Would measuring the dimensions of a solid always be possible? Explain.

I would like to see your reasoning and I will critique it; however, think about how accurately you can measure a regular solid versus how accurately you can measure a volume. Measuring a solid, of course, is not always possible except when it has a regular shape. That is, the volume of an irregularly shaped object must be determined some way other than by measuring its dimensions.

    hmmm...I just can't seem to get it. It looks like I got it right up to the volume of the metal point. Don't I have to divide the mass of the metal by the density of the water given before? (0.9970)? I guess I am having a problem
