DEC VAX had a single instruction for loading and storing all the program visible registers from/to memory. Can you see a reason for such an instruction pair? Consider both the pros and cons.
What will be an ideal response?
Pros: If you are a callee and need to use all of the temporary and safe registers, you can perform this operation in one call. If you want to save the current state of execution, it can be done in one call.
Cons: In most cases you do not need all available registers, so this command uses more memory (and possibly time) than required.

If bulk candy costs $10.00 a kilogram and 1 pound fills a box 5 inches by 3 inches by 2 inches, what is the weight of a box 3 inches by 4 inches by 5 inches that is full of candy?
Additional information: The volume of a rectangular box is the product of its three dimensions. Preliminary calculations vl (in3) = 5 (in.) * 3 (in.) * 2 (in.) = 30 (in3) v2 (in3)= 3 (in.) * 4 (in.) * 5 (in.) = 60 (in3)
