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
For this case we have a quadratic equation of the form:
What we must keep in mind to know which direction opens the parabola, is the value of a.
We have two options:
If a <0 the parabola opens down
If a> 0 the parabola opens up
We have the following equation:
We observed that:
Therefore, the parable opens up.
Answer:
the direction that this parabola opens is:
Upwards
