Question #260352

A School District has its own internal mail. However, it can’t accept packages that

weigh more than 0.5 kg or are larger than 0.2 cubic meters. Write a program that asks the user

to input the weight of a package and its three dimensions (length, width, and height) in meters.

If the package doesn’t meet the requirements, it should say why it failed, otherwise give a

success message.
