You got the first part right but you need the end so 4*3*1= 12 feet to turn feet into inch you times by 12 so 12*12=144 inc+99=243 cubic inc i think
Your function is: 
Domain: $(-\infty, +\infty)-\{ 0 \}$ or $R-\{ 0 \}$
Range: $[-\frac{3}{2}, -\frac{1}{2}]$
Midline: $y=-1$
If it takes him 90 minutes to read 5 and a half chapters, it would take him 16.36 minutes to read one chapter.
sqrt(200) ≈ 14.14213562373095
14 = 14
14/3 ≈ 4.666666666666667
From least-to-greatest:
14/3, 14, sqrt(200)
Can you tell me what shape that is and i will help as best as i can
