Answer:

450cm^{3}

Step-by-step explanation:

The volume of prism is Base times the height.

The Base you count from surface area. The formula is a*b/2. The a is 18/3, because you have the equilateral triangle. So you count 6*6/2 and get 18 square cm.  

After that you just multiply 18 and 25 and get 450cm^{3}

I hope this is right

emmasim [6.3K]
Here are my answers to the given questions above:
Part 1. Here is my example of a real life scenario that describes what is happening. Let us say, I have 2 cookies and the bottle of milk costs 11 dollars, and 3 cookies and 4 bottles of milk cost 24 dollars.
Part 2. 
y=11-2x
3x+4(11-2x)=24
3x+44-8x=24
-5x=-20
x=4
y=11-8
y=3
Therefore, each cookie costs 4 dollars, and a bottle of milk costs 3 dollars.
Hope this answer helps. Let me know if you need more help next time.
