Question

3.
Write a C++ program to input the side a of a cube, calculate and display its volume and
surface area. (Note. Volume = a?, Surface area = 6a²)

please answer it correctly
I really need it urgently.
if you give me the right answer then I will mark your answer as brainliest!
please please please help me!!!!​

Answer 1

Answer:

Examples:

Input : Side of a cube = 2

Output : Area = 8

Total surface area = 24

Input : Side of a cube = 3

Output : Area = 27

Total surface area = 54

// CPP program to find area

// and total surface area of cube

#include <bits/stdc++.h>

using namespace std;

// utility function

double areaCube(double a)

{

return (a * a * a);

}

double surfaceCube(double a)

{

return (6 * a * a);

}

// driver function

int main()

{

double a = 5;

cout << "Area = " << areaCube(a) << endl;

cout << "Total surface area = " << surfaceCube(a);

return 0;

}

THIS IS AN EXAMPLE ONLY.
