Need help with setprecision

[cmiller9732]

//#include "stdafx.h"
#include <iostream>
#include <iomanip>
using namespace std;

int main()
//int _tmain(int argc, _TCHAR* argv[])
{
double l;
double h;
double w;

//input

cout << " what is the length ";
cin >> l;
cout << " what is the height ";
cin >> h;
cout << " what is the width ";
cin >> w;

//output

cout << " the volume is " << setprecision(2) << l * w *h << endl;
cout << " the surface area is " << setprecision(2) << ( 2 * l * h ) + 2 * ( h * w ) + 2 * ( l * w) << endl;



return 0;
}



I need decimal places after my output.
thanks for any help

getch();
return 0;

im assuming your formulas are correct but this will fix your output issues
