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.

In order to determine the number of cans required to add up to 1 pound, it is necessary to divide the number of grams in a pound by the weight of an individual can. The quotient is equal to 30.442, meaning that it is necessary to round up to the nearest whole number which is 31.
