Answer:
72
Explanation:
Okay, you need to find two sides of this. The first one with 19 on the right, you have to subtract 19 and 11. The amount you get is what the answer will be.
19-11=8
The next one with 17 on the the bottom, you subtract 17 and 10. The amount you get is the answer.
17-10=7
Now you have all the sides you add them all up:
10+19+17+11+8+7
10+19=29
29+17=46
46+11=57
57+8=65
65+7=72
