Answer:
$20
Step-by-step explanation:
First we will change the ratio so that we are finding how much money Siti receives to the total amount of money.

We can see that the denominator increases 5 times, so the numerator must increase 5 times too. This means Siti receives $20.
FORMULA:
Volume of pyramid = L × B × H/3
Height of pyramid = 3V/area of base(L × B)
ANSWER:
So, we have to just plug the respective value.
Height of given pyramid = √(22.1² - 14²)
- √(488.41 - 196)
- √292.41 = 17.1m
Now, Volume of given pyramid = 28 × 28 × 17.1/3
