Answer: 191
Step-by-step explanation:
Formula to find the minimum sample size required to estimate a population proportion or percentage:

, where
= proportion estimated by prior study.
E= Margin of error.
z* = Critical z-value.
Given : Confidence level = 95%
Critical value for 95% confidence = z*=1.96

E= 7%= 0.07
Then, 


Hence, the minimum sample size required=191

Step-by-step explanation:
The surface area (x^2) that you will be provided as the base is made from the formula (3\sqrt(3)/2)s^2. s is the length of one side of the hexagon. In order to get surface area, you will also be provided the height of the prism. From there, set x^2=(3\sqrt(3)/2)s^2 and solve for s. Then multiply s * the height of the prism *8. Then, add 2x^2 to that value for total surface area/
