Question 1024992
The height of a rectangular box is 2 times its width, and its length is 
3in more than its width. The volume of the box is 130in3
find the width of the box
w = width
---
Vol = L*W*H
-----
Vol = w*2w*(w+3) = 130
2w^3 + 6w^2 = 130
w^3 + 3w^2 - 65 = 0
w is not an integer --> numerical solution.
--------
W =~ 3.323006
