a standard backpacked is approximately 20cm x 20cm x 35cm. suppose you find a hoard of pure silver while treasure hunting in the wilderness. How much mass would your backpack hold of filled with silver? An average students has a mass of 55 kg. How do theses values compare?

Answer 1

Solution:

Volume of backpack (V)= 20cm*20cm*35cm = 14000cm³

density of silver (P) = 10,40 g/cm³

mass of silver = P*V = 146,860 kg

146,860 kg/55kg = 2,8

Answer:

146,86 kg backpack would hold of filled with silver, that this is 2.8 times more than the student's weight.
