Answer:
V = 36 in³
Step-by-step explanation:
The volume of a rectangular prism is given by the formula V = l × w × h
Here our length is
, our width is 4, and our height is 
Plugging in these values to our formula give us 
V = 36 in³
To solve the inequality:

Add 1 to the sides of the inequality:

Then

Dividing all the inequality by 5, we have:

Graphically:
Or, in the interval notation(-1, 1/5).
