Answer:
width = 1.8 in
length = 3.6 in
height =
Step-by-step explanation:
A designer is making a rectangular prism box with maximum volume, with the sum of its length, width, and height 8 in
Let l , w and h are the length , width and height
Plug it in the first equation
volume the box is length times width times height
To get maximum volume we take derivatived
set the derivative =0 and solve for w
width = 1.8 in
length = 2w= 3.6 in
height =
