Question

Scrie un program in C++ care calc aria totala (At) , volumul (V) si diagonala (d) unui cub de latura l-reala data.

Answer 1

#include <iostream>
#include <cmath>
using namespace std;
int main(){
    int l;
    cin >> l;
    cout << "At: " << 6*l*l << "\n" <<
                 "V: " << l*l*l << "\n" <<
                 "d: " << l*sqrt(3);
    return 0;
} 

Answer 2

#include
#include
using namespace std;

int main() {
double l, V, d, At;
cin>>l;
At=6*l*l;
V=l*l*l;
d=l*sqrt(3);
if(l>0)
{cout< cout< cout< else
return 0;
}
