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.

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.
A single aluminum, 12 ounce can weights around half an ounce. This means, if you have a 12 pack of cans, it is going to weight about 6 ounces in aluminum. This is only about 4/10 of a pound, or in other words you are going to receive just over $0.34 for the 12 pack at 85 cents/pound.
