I am repeatedly getting wrong answer on this code. can someone tell me what is wrong with my code ??

#include <iostream>
#include <cmath>
#include <cstdio>

double area,ha,hb,hc,t;
cin>>t;

while(cin>>ha>>hb>>hc)
{

area=((ha*hb*hc)*(ha*hb*hc))/sqrt((hb*hc ...

can someone give me some critical inputs for this problem? I have tried some random udebug inputs. They all gave right answer. But when submitting i constantly getting WA.Thanks in advance
