Answer:![V=168\ units^3](https://tex.z-dn.net/?f=V%3D168%5C%20units%5E3)
Step-by-step explanation:
Given
Length of Prism ![l=6\ units](https://tex.z-dn.net/?f=l%3D6%5C%20units)
Height of prism ![h=7\ units](https://tex.z-dn.net/?f=h%3D7%5C%20units)
width of prism ![b=4\ units](https://tex.z-dn.net/?f=b%3D4%5C%20units)
Now Volume of a prism is given by
![V=l\times b \times h](https://tex.z-dn.net/?f=V%3Dl%5Ctimes%20b%20%5Ctimes%20h)
![V=6\times 4\times 7](https://tex.z-dn.net/?f=V%3D6%5Ctimes%204%5Ctimes%207)
![V=168\ units^3](https://tex.z-dn.net/?f=V%3D168%5C%20units%5E3)
150
Explanation: if you look at the chart it is going down 300 every 2 Months now just divide that by 2 to get the amount of one month and you get 150, Thus each month you pay 150.
The answer is the temperature goes down 2.8° every hour and the expression is x=-11.2/4 because 4 is how many hours between 6pm and 10pm and its -11.2 because that was how much the temperature dropped from 6pm to 10pm
