Basic cube area calculation (Expected a ")")

New to working with C++, just trying to do a cube calculation using 3 functions. However, when I call my calculation function in main, I get an error saying "Error: expected a ')'"

Not sure what's up.

using namespace std;

int getCubeSide();
void calcCube(int cubeSide);
void display(int cube);

int main()
{
     getCubeSide();
     calcCube(int cubeSide);
     display;

    system("pause");
}

int getCubeSide()
{
    int cubeSide = 0;
    cout << "Please enter an integer to calculate the size of your cube: " << endl;
    cin >> cubeSide;

    return cubeSide;
}

void calcCube(int cubeSide)
{
    int cube = (cubeSide * cubeSide * cubeSide);

}

void display(int cube)
{
    cout << "The area of your cube is: " << cube << endl;
}
