//V=sqrt((4*a*a*b*b*c*c-a*a*(b*b+c*c-m*m)*(b*b+c*c-m*m)-b*b*(c*c+a*a-n*n)*(c*c+a*a-n*n)-c*c*(a*a+b*b-l*l)*(a*a+b*b-l*l)+(a*a+b*b-l*l)*(b*b+c*c-m*m)*(c*c+a*a-n*n)))/12
//a=AB,b=AC,c=AD,l=BC,m=BD,n=CD;
#include<stdio.h>
#include<math.h>
int main()
{
 double a,b,c,l,m,n;
 double V;
 while(scanf("%lf%lf%lf%lf%lf%lf",&a,&b,&c,&l,&m,&n)!=EOF)
 {
 V=pow(4*a*a*b*b*c*c-a*a*(b*b+c*c-m*m)*(b*b+c*c-m*m)-b*b*(c*c+a*a-n*n)*(c*c+a*a-n*n)-c*c*(a*a+b*b-l*l)*(a*a+b*b-l*l)+(a*a+b*b-l*l)*(b*b+c*c-m*m)*(c*c+a*a-n*n),0.50000);
 V/=12.0;
 printf("%.20lf\n",V);
 }
 
}
