the cube is made of 800/1000 pure silver. Assume that silver has a density of 10.5 g/cm3 and a price of 0.68Euro/g. Calculate the value of the silver partion?
Haven't studied math since 15 years so I'd appreciate if someone could explain this question. Thanks in advance!
Here are the steps along the way. YOu can do the arithmetic.
Find the volume (in cubic centimeters) of the cube (use the side length)
Find the volume that is silver (you're told the fraction of the whole) (But if the given fraction is the weight fraction rather than the volume fraction you are stuck, as @RossMillikan comments,)
Find the weight of the silver (you know the density in grams per cubic centimeter)
Find the value (you know the price in Euros per gram)
