Write a C++ program that calculates the volume of a rectangular tank at different volume requirements. Your program will prompt the user to input: two dimensions of the bottom of the tank, thickness of the material to make the tank, volume that the tank is required to hold density of the fluid. The program will calculate the tank height required to hold the fluid and the total weight of the tank plus fluid. Include plenty of comments in your program. Your program should clearly tell the user what kind of input is required. Test the code using three tank sizes of your own. For each tank size, use three different materials. Draw a hand sketch of each tank showing all dimensions, the density of the fluid, tank weight, fluid weight and total weight. Use inch pounds for units.
