Which of the following has a similar volume to that of the total amount of platinum ever produced?

Question

Platinum is a very rare metal, ever rarer than gold. It's density is 21.45 g/cm^3. Assuming that the world production has been about 10 tonnes every year for the past 50 years, and very little before that, which of the following has a similar volume to that of the total amount of platinum ever produced?

a) a shoe box

b) a cupboard

c) a house

d) a palace

e) the Grand Canyon

how did u get ur answer. please show how you got ur answer please. thx = )

Answer 1

total Pt production=50*10=500 tons=500,000,000 g

density=21.45g/cm^3

vol=mass/density=500,000,000/21.45=233... cm^3=23.31 m^3

So the probable answer is cupboard...
