{printf("please inputn");

printf("a=");scanf("%f",&a);

printf("b=");scanf("%f",&b);

printf("c=");scanf("%f",&c); ;

printf("this superficial area=%fn",2*(a*b+a*c+b*c));

printf("n");

fflush(stdin);

printf("hit'Y'input again(or 'N' end):");

scanf("%c",&t);

sa=sa+2*(a*b+a*c+b*c);

}

printf("n");

printf("the totle superficial area=%fn",sa);

fflush(stdin);

printf("price=");scanf("%f",&p);

sum=sa*p;

printf("the totle sum=%fn",sum);

system("pause");

}
