Every year about 20,000 pounds of stone, sand and gravel are mined for each person in the United States. Calculate how many pounds of stone, sand and gravel will be needed for an individual during a 75 year life span. Since a cubic yard of rock of rock weighs roughly 1,700 pounds, how big a hole must be dug to supply an individual with 75 years' worth of stone, sand, and gravel?
I have figured out a bit of it myself.
Such as after 75 years, 1500000lbs of sand, stone and gravel would be had.
I am stuck? We were assigned lab partners, but I chose to work alone.
