A rectangular box with no top is to be built from 1728 square meters of material. Find the dimensions of such a box that will enclose the maximum volume.

given surface area with no top as 1728

We say

V= X x Y x Z

So

yz = a(y+2z)

xz = a(x+2z)

Then using partial derivatives

xy = a(2x+2y)

xy+2xz+2yz = 1728

So

xy+2yz = xy+2xz

x=y

So

4xz = x²+ 2xz

x = 2z

4z²+4z²+4z²= 1728

z² = 432

z = 20.8m

x = y = 41.6m

there is no picture

step-by-step explanation:

put up a picture so people can you

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
