Question
surface_area.cpp
Write a program that computes the surface area of a rectangular solid. Your program should prompt the user to input the length, width, and depth of a rectangular solid. It should then compute the surface area of the rectangular solid and print the area for the user (with a good message).
Use double-type variables for each value. You may assume the user input is error free. When you prompt for and report the measurements, you should use a measurement unit of your choice such as meters, inches, etc. (The user should not enter units, just three values.)
