Volumn = Height*Width*Length
Width*(Width+2)=Volumn/Height=240/3=80
Width^2 +2Width-80=0
(Width-8)(Width+10)=0
Width>0 -> Width+10>0
-> Width-8=0 -> Width=8 inches

Greetings from Brasil...

Here are the operations found:

4y = 4 · y → multiplication of 4 by y

7/d = 7 ÷ d → 7 by d division

t + 8 → sum of t with 8

3 + t → sum of 3 with t
