1. C. Concave pentagon
2. A. 1620°
b/c (11 - 2) × 180 = 1620
3. B. 165°
b/c (24 - 2) × 180 ÷ 24 = 165
4. A. 160°
b/c (18 - 2) × 180 ÷ 18 = 160
This question is essentially asking you to find the surface area of the box.
The formula for SA on a rectangular prism is: 2(L*W+L*H+W*H)
L=Length W=Width H=Height
Lets input the information we know:
2(20*8+20*30+8*30)
Follow BEDMAS
2(160+600+240)
2(760+240)
2(1000)
2*1000
=2000
The box will need 2000 centimeters squared of material.
Hope this helps!

Answer:
The probability is 1
Step-by-step explanation:
Given
Number of flips = 8
Outcomes = 8 heads
Required
Probability of getting a head in the next row
This problem can be attributed to experimental probability and it'll be solved using experimental probability formula, which goes as follows;
![Probability = \frac{Number\ of\ Occurence}{Total\ Trials}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7BNumber%5C%20of%5C%20Occurence%7D%7BTotal%5C%20Trials%7D)
Let
represents the probability of getting a head in the next row;
![P(Head)= \frac{Outcome\ of\ head}{Total\ Flips}](https://tex.z-dn.net/?f=P%28Head%29%3D%20%5Cfrac%7BOutcome%5C%20of%5C%20head%7D%7BTotal%5C%20Flips%7D)
![P(Head)= \frac{8}{8}](https://tex.z-dn.net/?f=P%28Head%29%3D%20%5Cfrac%7B8%7D%7B8%7D)
![P(Head)= 1](https://tex.z-dn.net/?f=P%28Head%29%3D%201)
Hence, the probability of obtaining a head in the next flip is 1
