Enter the dimensions of a rectangular box with a volume of 50b3 - 3 - 2b + 75b2.

 (5b - 1)(5b + 1)(2b + 3)

phi · Answer

First,  if a box has width, length and height
and the box exists,  can the width (for example) be zero ?  Can the width be negative ?

I think it can, but I'm trying to see what b is to make the sentence. I'm not too sure on the logistics of it, because there is no constant answer.

no
