A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core, which stores copies of the data from frequently used main memory locations.
It takes approximately 31 empty aluminum cans to equal 1 pound. As of 2014, the average weight of an empty aluminum can is 14.9 grams.
You will know exactly how many cans you need. If you wish to make $10, and the current scrap rate is 50 cents /lb you would divide $10 by 50 cents, (10 / .50) which of course equals 20. Now take that 20 and multiply it by the number of cans in a pound (34), so it would be 20Ã34 which equals 680. So (10/.50 = 20) and then 20Ã34=680; you would need 680 empty 12 ounce aluminum cans to generate $10.
