I having trouble defining surface area and volume in the same function for the problem I was given. Any assistance would be greatly appreciated. Thanks

Complete the program below that calculates the surface area and volume of a rectangular solid based on its length, width, and height. Define function rectangleAreaVolume.

#include using namespace std;

// Put your function prototype here. double surfaceArea(double, double, double);

int main() { double length; double width; double height; double sArea; double vol;

cout << "Enter the length of the rectangular solid => "; cin >> length; cout << "Enter the width of the rectangular solid => "; cin >> width; cout << "Enter the height of the rectangular solid => "; cin >> height;

rectangleAreaVolume(__________________, ___________________,

____________________, ____________________, _________________);

cout << "Surface area = " << sArea << " square units." << endl; cout << "Volume = " << vol << " cubic units." << endl;

return 0; }

// Calculates the surface area and volume of a rectangular solid. // Put your function definition here.

double surfaceArea(double length, double width ,double height) { double sArea = 2 * ((length * width) + (length * height) + (width * height));

}
