Thirty elves would like to build a skating rink, so they can all use it at the same time. Santa tells them, they need at least 4
0 square feet for each skater, so no one will bump into each other. If they build a rectangular rink, what are some possible dimensions (length and width) for the rink?

So we will be using form, in which m = slope and b = y-intercept. Since we know the slope (-8), all we need to do is solve for the y-intercept. We can do this by inserting (-2,2) into the equation and solve for b.
Firstly, do the multiplication:
Next, subtract 16 on both sides, and your answer will be -14 = b
Using the previous info we have, our equation is y = -8x - 14
The volume of the rectangular prism is
Where:
L is its length
W is its width
H is its height
From the given figure
L = 15.2 cm
W = 8 cm
H = 5.8 cm
Substitute them in the rule above
Round it to the nearest tenth
