Java program as below.

Answer:

"#include <bits/stdc++.h>

using namespace std;

 // utility function

double areaCuboid(double l, double h, double w)

{

   return (l * h * w);

}

 double surfaceAreaCuboid(double l, double h, double w)

{

   return (2 * l * w + 2 * w * h + 2 * l * h);

}

 // driver function

int main()

{

   double l = 1;

   double h = 5;

   double w = 7;

   cout << ""Area = "" << areaCuboid(l, h, w) << endl;

   cout << ""Total Surface Area = ""

        << surfaceAreaCuboid(l, h, w);

   return 0;

}
