Answer: A. 184.8ft2

Step-by-step explanation:

The pyramid is made up of four sides that are rectangular, each side has a height of 12.4ft and base length of 6ft.

The base area is a square of 6ft by 6ft.

For the sides, area of a triangle is 1/2 x base x height

= 1/2 x 6 x 12.4 = 37.2m2

For the four triangles = 4 x 37.2 = 148.8m2

For the square base, area is 6 x 6 = 36m2

Total surface area = 148.8 + 36 = 184.8ft2

The correct anwer is False

Explanation

According to the graph, it can be seen that a student has four hours of sleep as the minimum number of hours of sleep; two students have six hours of sleep, four students have six and a half hours of sleep, four have seven hours of sleep, three have seven and a half hours of sleep, five have eight hours of sleep, and one has eight and a half hours of sleep as maximum hours of sleep. Therefore, it can be affirmed that the statement that the difference between the maximum amount and the minimum number of hours is two and a half hours is false because between four hours and eight and a half hours there are four and a half hours of difference. So, the correct answer is False.
