Answer:
![SA=592.50\text{ ft}^2](https://tex.z-dn.net/?f=SA%3D592.50%5Ctext%7B%20ft%7D%5E2)
Step-by-step explanation:
We have been given that a square pyramid has a base with a side length of 7.5 feet and lateral faces with heights of 16 feet. We are asked to find the surface area of the square pyramid.
We will use surface area of square pyramid to solve our given problem as:
, where,
a = Length of each side of base,
h = Height of lateral face.
Upon substituting our given values in above formula, we will get:
![SA=2(7.5\text{ ft})^2+4(7.5\text{ ft})(16\text{ ft})](https://tex.z-dn.net/?f=SA%3D2%287.5%5Ctext%7B%20ft%7D%29%5E2%2B4%287.5%5Ctext%7B%20ft%7D%29%2816%5Ctext%7B%20ft%7D%29)
![SA=2(56.25\text{ ft}^2)+480\text{ ft}^2](https://tex.z-dn.net/?f=SA%3D2%2856.25%5Ctext%7B%20ft%7D%5E2%29%2B480%5Ctext%7B%20ft%7D%5E2)
![SA=112.5\text{ ft}^2+480\text{ ft}^2](https://tex.z-dn.net/?f=SA%3D112.5%5Ctext%7B%20ft%7D%5E2%2B480%5Ctext%7B%20ft%7D%5E2)
![SA=592.50\text{ ft}^2](https://tex.z-dn.net/?f=SA%3D592.50%5Ctext%7B%20ft%7D%5E2)
Therefore, the surface area of the given square prism would be 592.50 square feet.
So, in this problem, we simply need to subtract.
9,162 - 969 = 8,193
8,193 is your answer.
Glad I could help, and good luck!

Answer:
2 + (−7) = −5, because −5 is 7 units to the left of 2
Step-by-step explanation:
Point S is on 2 on the number line shows Samuel's score after the first round of a quiz. In round 2, he lost 7 points
At first point S is 2 on the number line
So S is 2
in the second round he lost 7 points
for lost , subtract 7 from 2
![2-(7)=-5](https://tex.z-dn.net/?f=2-%287%29%3D-5)
so the point S is on -5 on round 2
2 + (−7) = −5, because −5 is 7 units to the left of 2
Answer:
its 92.5, dont forget that decimal point
Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
Width of key in student calculator = 14 millimeter (1.4 cm)
Width of key in demonstration calculator = 2.8 cm
Thus, the demonstration calculator's dimensions are twice that of students' (in cm)
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
