Answer:
The program is as follows:
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
    int num1, num2, num3;
    cin>>num1>>num2>>num3;
    cout << fixed << setprecision(2);
    cout<<(num1 + num2 + num3)/3<<" ";
    cout<<num1 * num2 * num3<<" ";
    return 0;
}
Explanation:
This declares three integer variables
    int num1, num2, num3;
This gets input for the three integers
    cin>>num1>>num2>>num3;
This is used to set the precision to 2
    cout << fixed << setprecision(2);
This prints the average
    cout<<(num1 + num2 + num3)/3<<" ";
This prints the product
    cout<<num1 * num2 * num3<<" ";
 
        
             
        
        
        
Answer
 sorry I only know how to make balloons :(
Explanation:
For the balloons the recipe that one is:
- you will need 6 latex 
To make latex you will need two different elements one is 5 Carbon and the other one is 8 Hydrogen ( don't use crafting table to do it use the compound creator)
-Dye ( whatever color you want)
-Helium
-lead 
Instructions
on the crafting table the latex will go on the sides (3 on the left and 3 on the right). The dye goes on top, the Helium in the middle and the lead at the bottom and there you go a balloon
