Answer:
288 km²
Step-by-step explanation:
The surface area is the sum of the area of the square base and the area of the four triangular faces.
SA = (10 km)² + 4(1/2)(10 km)(9.4 km) = 288 km²
____
The area formulas for a square and a triangle are ...
A = s² . . . . area of a square of edge length s
A = 1/2bh . . . . area of a triangle with base b and height h
To answer this item, find first the z-score of the given data.
z-score = (x - m) / d
where x is data point, m is the mean and d is the standard deviation
Substituting the given values,
z-score = (188 - 176.7) / 9.9 = 1.14
This translates to a percentage of 87.29%.
Because we are asked of the percentage of those with height greater than this, that would be,
100 - 87.29% = 12.71%
Answer: 12.71%
