Check the picture below. Recall, is an open-top box, so, the top is not part of the surface area, of the 300 cm². Also, recall, the base is a square, thus, length = width = x.

so.. that'd be the V(x) for such box, now, where is the maximum point at?

now, let's check if it's a maximum point at 10, by doing a first-derivative test on it. Check the second picture below.
so, the volume will then be at
Answer:
- 13.077
Step-by-step explanation:
Here we have to calculate the square root of a certain number using the help of the calculator or a square root table.
The given expression is
.
Now, using calculator
Now,
So, approximate value to the nearest thousandth is - 13.077 ( Answer )
It is rounded to the nearest tens. You can only round when you have 1,9. Hope I helped
Answer:
both angles are the same, so you can use it interchangeably in proving.
But i suggest you to mantain only one, because it's easier to understand and it looks better.
Just plot the points on a graph.
