Got what?

- anonymous

wait a second

- anonymous

I got my dementions

- anonymous

i got my box

- AbdullahM

ok

- anonymous

its L= 30cm W= 21cm

- AbdullahM

There has to be another dimension. What is the height?

- anonymous

30cm

- anonymous

hey ? would you get you hieght from the base up.

- anonymous

actualy the box is standing up

- AbdullahM

Found a better picture

- anonymous

ok so my with would be 13

- anonymous

i just measured it.

- anonymous

i mean hight

- AbdullahM

L= 30cm
W= 21cm
H= 13 cm

- AbdullahM

Surface Area of a Rectangular Prism = 2LW + 2LH + 2WH

- AbdullahM

So calculate the Surface Area using the dimensions and that formula I just posted.

- anonymous

yes i am calculating one second.

- anonymous

hey is it 2lxw

- anonymous

it is 68147

- AbdullahM

How did you get that?

- anonymous

al i did was did what you told me

- anonymous

abdullahM

- anonymous

but i dont get it am i apost to add them up, x and then ad what.

- anonymous

?

- AbdullahM

\(\sf\Large (2\times 30\times 21) + (2 \times 13 \times 21) + ( 2\times 13 \times 30)=?\)

- anonymous

i new it hey ty

- anonymous

but still not done

- anonymous

134365920

- AbdullahM

how are you getting such huge numbers?

- AbdullahM

ok, lets do this part by part

- anonymous

ok

- AbdullahM

what is
\(\sf\Large (2\times 30\times 21) =?\)

- anonymous

1260

- AbdullahM

ok, now what is:
\(\sf\Large (2 \times 13 \times 21)=?\)

- anonymous

546

- AbdullahM

and finally what is
\(\sf\Large ( 2\times 13 \times 30)=?\)

- anonymous

780

- AbdullahM

and now finally what is:
\(\sf\Large 1260 +546 +780=?\)

- anonymous

2586

- AbdullahM

and that's your surface area...

- anonymous

ok ty

- AbdullahM

|dw:1435414080138:dw|

- AbdullahM

erm let me fix that picture, brb

- AbdullahM

|dw:1435414559024:dw|

- AbdullahM

there we go

- AbdullahM

so what would be the cross section?

- AbdullahM

hello....

- anonymous

it is square AbdullahM

- anonymous

excuse me but can i gett alittle bit of assistance please.

- anonymous

xapproachesinfinity

- anonymous

so u r going 2 sit ther and wait, for what?

- AbdullahM

well in the example it is a square, but for your question it would have to be a rectangle.

- anonymous

ok ty

- AbdullahM

for #4, multiply the surface area (2586) by 10

- anonymous

it is 25860

- anonymous

ok

- anonymous

AbdullahM

- AbdullahM

correct

- AbdullahM

what is the formula for calculating volume? it's an easy formula :)

- AbdullahM

yohooo, I don't got all day...

- anonymous

hey bro i am sorry my computer is kicking mmy butt and i had to walk my dogs.

- anonymous

AbdullahM

- AbdullahM

The volume of a rectangular prism is the length on the side times the width times the height.

- AbdullahM

so what is the volume for this box?

- AbdullahM

\(\color{blue}{\text{Originally Posted by}}\) @AbdullahM
L= 30cm
W= 21cm
H= 13 cm
\(\color{blue}{\text{End of Quote}}\)
