Thread: quadradic

I have this question and i'm having a hard time:
- Open-top boxes are constructed by cutting equal squares from the corners of cardboard sheets that measure 32cm by 28cm. Determine dimensions of the box if each has a volume of 1920 cm^3.

THANKS alot

let x = side length of a cut-out square

LWH = V

(32-2x)(28-2x)x = 1920

ok i get what u do, lol can u please solve it for me cause i'm not sure how too,.

my calculator says x = 4 or x = 6 will work.

sorry for my retarded ness, but do u foil them? or do u sub in 4 and 6"? MAN I"M SO STUPID
