Write a c++ program to calculate the surface area, volume, or \"girth + depth\"

Question

Write a c++ program to calculate the surface area, volume, or "girth + depth" of a box. The formulas are as follows: volume= length*width*depth. surface area =2lw+2wd+2ld. Girth+depth= 2(l+w) +d . (girth+depth is used in shipping). The input of the program will be a letter. "v" will indicate volume, "a" the surface area, "g" the firth plus dpeth, and "q" to stop the loop (Q is the sentinel) the second part of the input will be a three (float) numbers representing the length, width, and depth respectively. for each input, just calculate what is called for, not all three answers. Use nested if-elses, or a switch structure to control your actions. The output should have appropriate labels. Use format to control the appearance of your answers. Use sentinel loops to read the data. The Q for the operation will be the sentinel. The program should work for any data set, not just the data set below. Libraries: iostream, iomanip.

Input: A 1.0 2.0 3.0
G 5.0 4.0 3.0
V 2.3 4.9 6.7
A 3.7 4.3 9.6
Q
