assuming there are 7.481 gallons in a cubic foot, write a program that ask the user to enter a number of gallons and then display equivalent in cubic feet.
#include <iostream>
using namespace std;
int main (){
cout <<"enter a number of gallons\n";
double x ; cin>>x;
cout << "equivalent in cubic feet:& " << x * 7.481 << endl;
system("pause");
return 0;
}
