Mensuration sums calculator

This source code is written in Java and is about solving mensuration problems by giving the required inputs. We have imported util package in order to use the scanner class. The program run on the principle of nested switch loops as we have different shapes and different choices, based on the problem you need to solve choose the options given accordingly. On the choice of option, please give the required input in order to find the needed answer. Please use an offline compiler in order to run this program as it may be difficult to work with importing packing in online compilers.
