Rhodium metal currently costs $1251. per troy ounce (note this is different than a regular ounce! 1 troy ounce = 31.1035g). What would the cost be in dollars to purchase enough gold to form a solid square based pyramid with base dimensions 0.750m by 0.750m and height of 0.500m?

Do you want gold or rhodium? I'm confused by the problem.
I am too, gold, I think. thanks sooo much for your help
For Au. I would change the dimensions to cm so the volume comes out in cc.
volume square based pyramid is
V = (1/3)*(b^2)*h = ?cc
Look up the density of Au in g/cc and
mass Au = density Au x volume from above.
Using the conversion from grams to troy oz, convert to troy oz, then
cost/troy oz x #troy oz = cost of the pyramid in Au. But I wonder what's the point of all of the information on Rh.
