Chapter 3.6, Problem 6E

(General math) The perimeter, approximate surface area, and approximate volume of an in-ground pool are given by the following formulas:

$\begin{array}{l}perimeter=2\left(length+width\right)\hfill \\ volume=length\times width\times averagedepth\hfill \\ undergroundsurfacearea=2\left(length+width\right)averagedepth+length\times width\hfill \end{array}$

Using these formulas as a basis, write a C++ program that accepts the length, width, and average depth measurements, and then calculates the pool’s perimeter, volume, and underground surface area. In writing your program, make these two calculations immediately after entering the input $data:length\times widthandlength+width.$ The results of these two calculations should be used as needed in the assignment statements for determining the perimeter, volume, and underground surface area without recalculating them for each equation. Verify your program’s results by doing a hand calculation, using the following test data $:length=25feet,width=15feet,andaveragedepth=5.5feet.$ After verifying that your program is working, use it to complete the following chart:
