@thivitaa @Spectrum

OpenStudy (anonymous):

i did the first 2 on the second link

OpenStudy (anonymous):

surface area

OpenStudy (anonymous):

please help me!

OpenStudy (anonymous):

the links are not spam i promise

OpenStudy (anonymous):

I can do it if you want

OpenStudy (anonymous):

i tookpictures of mgy assignment

OpenStudy (anonymous):

well the base question....with noah

OpenStudy (anonymous):

yes please i beg uu

OpenStudy (anonymous):

think about each side as just a square of l x w

OpenStudy (anonymous):

ive many more things to do before 8:00 am

OpenStudy (anonymous):

(its 5:00 am where i am)

OpenStudy (anonymous):

6 squares 3 pairs 2 l x w 2 w x h 2 h x l right?

OpenStudy (anonymous):

umm...yes, i think,what priblem is it?

OpenStudy (anonymous):

2(50x25) + 2(25x20) + 2(20x50) = total square feet

OpenStudy (anonymous):

first one top question

OpenStudy (anonymous):

umm. can we dl the thrrd orn e on the second elink?

OpenStudy (anonymous):

the triangular prism?

OpenStudy (anonymous):

yes and the fourth as well

OpenStudy (anonymous):

plz?

OpenStudy (anonymous):

yeah hold on please

OpenStudy (anonymous):

ok btw u did the wuestion about neah on the first link?

yes, plz look at the second link

OpenStudy (anonymous):

i got help onnthe first two on that one

OpenStudy (anonymous):

calm down okay lets do 4 first

OpenStudy (anonymous):

if its a perfect cub all you need is (3.5^2)6

OpenStudy (anonymous):

okay srry its just that everyonr was abandoning my q yesterday

OpenStudy (anonymous):

ok, that formula for everything?

OpenStudy (anonymous):

no but its a cube...it has 6 of the same exact sides all the sides are the same length ..and one face would be 3.5 x 3.5 ...6 sides would be 6 (3.5 x 3.5)

OpenStudy (anonymous):

because it asks for p perimeter of the base b area of the base lateral surface area and total surface area

OpenStudy (anonymous):

oh ok

OpenStudy (anonymous):

i understand that.

OpenStudy (anonymous):

area of base would be 3.5 x 3.5 and permiter of the base would be all the sides of the base or 3.5 x 4

OpenStudy (anonymous):

ok, let mme write those down real quick

OpenStudy (anonymous):

ok done

OpenStudy (anonymous):

3.5^2

OpenStudy (anonymous):

um, that is for,,,,,

OpenStudy (anonymous):

what ws tgat for?

OpenStudy (anonymous):

sorry im lagging holdon

OpenStudy (anonymous):

what measurement,i mean

OpenStudy (anonymous):

ook

OpenStudy (anonymous):

it was for totall surface area it was 6(3.5^2)

OpenStudy (anonymous):

o ok leg me calculate

OpenStudy (anonymous):

ok 73.5

OpenStudy (anonymous):

what part of three are you having trouble iwht?idk what l s.a is

OpenStudy (anonymous):

umm,umm, yes, total surface area, will u plz help mme with number three?

OpenStudy (anonymous):

no i mean lateral

OpenStudy (anonymous):

oh s.a. means surface area

OpenStudy (anonymous):

is the lateral surface area 49 for number 4?

OpenStudy (anonymous):

what do you mean by lateral?

OpenStudy (anonymous):

lateral surfacd area.

OpenStudy (anonymous):

what is that?

OpenStudy (anonymous):

surface*

OpenStudy (anonymous):

emcrazy do you know what that is?

OpenStudy (anonymous):

spectrum it is perimeter of base times height

OpenStudy (anonymous):

well that would be the permiter times 3.5

OpenStudy (anonymous):

umm, 14 x 3.5 ok let me calculate

OpenStudy (anonymous):

49?

OpenStudy (anonymous):

correct :)

OpenStudy (anonymous):

and total you said was 73.5

OpenStudy (anonymous):

its 6(3.5 x 3.5)

OpenStudy (anonymous):

oh :) so thats what i do for laterall, yes?

OpenStudy (anonymous):

ok. now let us do the one about the birthday present,yes?

OpenStudy (anonymous):

oh it does not show the problem is a presrnt has a length of 14 inches width of ten inches and height of seven inches, what is the minimum amount of wrapping paper needed to wrap the present?

OpenStudy (anonymous):

so its like a rectangular prism

OpenStudy (anonymous):

help me plz!

OpenStudy (anonymous):

um sorry im getting tired..i will do this one ..buts thats it...... basically is 2(lx w) + 2( l x h) + 2( h x w) dude..you are going to have to calm down....seriously..or i won't help you again.

OpenStudy (anonymous):

Fine. okay. and my name is rachel.

OpenStudy (anonymous):

i am calm.

OpenStudy (anonymous):
