So we already know that one of the numbers, the largest, is 7. Now we just need to find the other 3. The other 3 numbers add up to 10. So, we can divide 10 by 2 to get 5. What odd and even numbers equal five? 2 and 3.
I think it’s 36 Explanation if all parts are equal then since there are 9 parts in total then each part is 4 grams and since there’s 3 adhesive parts it’s 12 grams in total and 12x3 = 36 hope this helped
