Question 616611
let us say that the width is 'w'.
the height is therefore w+2

As Volume = height x width x length then:

3960 = (w+2) x w x 33

I always find it better to have the whole numbers to the right:

(w+2) x w x 33 = 3960
33w(w+2) = 3960
{{{33w^2 + 66w = 3960}}}

{{{33w^2 + 66w - 3960 = 0}}}

Divide each value by 33 to simplify:

{{{w^2 + 2w - 120 = 0}}}

(w + 12)(w - 10) = 0

Therefore w = -12 or w = 10

as w has to be a positive number due to it being a measurement of a real length then w = 10

Therefore width = 10 in. and height is two more than this so = 12 in.

To check result

12 x 10 x 33 = 3960 !!!
