Surface Area (S.A.) is the area of all of the faces.
The base is square so its area is: side² = 8 cm x 8 cm = 64 cm²
The faces are triangles so the area of ONE face is: (1/2) x base x height =
(1/2)(8 cm)(14 cm) = 56 cm²

The sum of all of the faces are 64 cm² + 4(56 cm²) = 64 + 224 = 288 cm²

Answer: the surface area of the square pyramid is 288 cm²

Answer:

There are 25 students in the class.

Step-by-step explanation:

In order to find the number of students in the class, you can add the number of data points together. Because the name of each person will only be recorded once and only to one data value, that means by adding the total number of data points collected, you can find out the number of students in the sixth-grade class. There are three data points on 3, two data points on 4, five data points on 5, eight data points on 6, two data points on 7, one data point on 8, and four data points on 9, this means the total number of students will be 3 + 2 + 5 + 8 + 2 + 1 + 4 = 25 students, so this will be your answer.
