Step-by-step explanation:
The volume of the box is given as
, where
and
.
Expand the function to obtain:

Differentiate wrt x to obtain:

To find the point where the maximum value occurs, we solve



Discard x=3.54 because it is not within the given domain.
Apply the second derivative test to confirm the maximum critical point.
, 
This means the maximum volume occurs at
.
Substitute
into
to get the maximum volume.

The maximum volume of the open box is 24.26 cm³

Helloooo, Your answer for part A is 13 cm
You answer for part b is 2600
13 x 10 x 20 = 2600
4/11 * 10/8
= 1/11 * 10/2
= 1/11 * 5
= 5/11
answer 5/11
you got it correct
