題解：

一個制造商生產正方形底的紙箱，箱頂是兩塊扇掩式的箱蓋。底部因要加強強度而造成雙層的。每個箱的體積是12立方米。

(a)

證明C（做一個箱所需的紙板面積）=3^2

+

4xh

(b)

表達C作為只有x的函數

?

順著x>0描繪C的圖表

(d)

(i)

什么尺寸的箱會讓所需造箱的紙板面積最少化？

(ii)

用來造箱的最少紙板面積是什么？

After

explaining

the

question,

we

are

going

to

answer

them

as

shown

below:

(a)

Ignor99de

the

fact

that

the

top

is

a

flap

opening,

the

two

flaps

combine

to

form

one

complete

surface.

Taking

into

account

that

the

bottom

is

double-layered,

that

means

the

box

has

in

total

7

surfaces.

So,

we

have

C

=

3*x^2

(1

top

+

2

bottom)

+

4*x*h

(4

side

faces)

Therefore,

C

=

3x^2

+

4xh

(b)

As

given,

the

volume

of

the

box

should

be

12

m^3,

that

means

12

=

x^2*h

h

=

12/x^2

Put

into

C,

then

C

=

3x^2

+

4x(12/x^2)

Simplify,

we

get

C

=

3x^2

+

48/x

?

Sorry,

I

do

not

know

how

to

upload

pictures

here!

(But

this

should

not

be

difficult!)

For

your

easy

following,

make

the

following

table

and

plot

the

points

accordingly:

(From

the

graph,

we

could

already

see

that

the

minimum

C

occurs

at

around

x=2.)

I

am

not

sure

whether

you

have

learn

differentiation

or

not.

Anyway,

if

you

have

not

learnt

yet,
