If you have more questions about math... just ask me!
Since u need the surface area of a rectangular prism it is length•width•height so the answer is 24 feet squared
The answer to your question is 70.08
Changing the “m” or “b” would change the overall line on the graph. Meaning the line could be steeper or flatter. It could also change whether the line has a positive slope or negative. Likewise, when you use negative numbers for the m, the line will have a negative slope and will have a decreasing look to it. When you use negative numbers for the b, the y-intercept will be negative which will put the line further down the y-axis.
I hope this is what you were looking for! I kinda did it off the top of my head so of course feel free to change anything!!
