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.
The interest is $58,760.84
The total is $133,760.84

Answer:
8 quarts
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Water = 2 quarts
Orange Juice = 1quarts
Mango Juice = 2 quarts
Strawberry juice = 1 quart
Pineapple Juice = 2 quarts
So, Total mixture = Sum of all ingredients in quarts
= 2 + 1 + 2 + 1 + 2 = 8 quarts
Hence, Maria makes 8 quarts of punch.
