Surface Area of the square = 8 x 8 = 64 cm²
Surface Area of the 4 triangle = 4 x [ 1/2 x 8 x 14]
Surface Area of the 4 triangle = 4 x [ 56]
Surface Area of the 4 triangle = 224 cm²
Total Surface Area = 64 + 224 = 288 cm²

Answer:
99% confidence interval will be wider because as the level of confidence increase the width increases as well and the standard error decreases
Step-by-step explanation:
The confidence interval is directly proportional to the sample size hence the 99% confidence interval will be wider than the 95% confidence interval of the sample of 120 college students
using a 99% confidence interval gives a more accurate result than a 95% confidence because the standard error decreases with increase in confidence interval
50% of 18 = 9
so buy 1 for 18 and 1 for 9 = 18+9 = 27 for 2 sheets
6/2=3
27 x 3 = 81 for 6 sheets
