Find at least five regular household items that are shaped like rectangular prisms or cylinders. You must have at least one prism and one cylinder.

OpenStudy (anonymous):

For a prism, identify the length, width, and height. Use an appropriate unit of measure for measuring your object. Round all measures to the nearest whole number. For a cylinder, identify the height and diameter of the base. Use an appropriate unit of measure for measuring your object. Round all measures to the nearest whole number. Determine the surface area of your object. Show all work and label your answer using the correct unit of measure. Determine the volume of your object. Show all work and label your answer using the correct unit of measure.

OpenStudy (anonymous):

Name the object. Identify the shape of the object (prism or cylinder). Draw a sketch and give the dimensions of the object

OpenStudy (anonymous):

Hold on

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

can you give me a picture of the prism?

OpenStudy (anonymous):

ok just any picture

OpenStudy (anonymous):

OpenStudy (anonymous):

OH my...

OpenStudy (anonymous):

what

OpenStudy (anonymous):

@Anthony2992992

OpenStudy (anonymous):

please help

OpenStudy (anonymous):

I don't even know what you guys are trying to figure out.

OpenStudy (anonymous):

i will tell you wait

OpenStudy (anonymous):

@Chiko_1278

OpenStudy (anonymous):

just so you know its kind of like a project

OpenStudy (anonymous):

please help me

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

but can you do something for me

OpenStudy (anonymous):

hold on i am going to put a pic of to house hold things

OpenStudy (anonymous):

ok so It says that you have to find 5 items in your house that are shaped like a rectangular prism or cylinder. right.

OpenStudy (anonymous):

yeah it does

OpenStudy (anonymous):

so go around your house and find stuff. look up a picture and compare the stuff you find with the picture

OpenStudy (anonymous):

here are the too pics

OpenStudy (anonymous):

ok that's a start but is that what you found in YOUR house and not on just on the internet

OpenStudy (anonymous):

ok so which one are you going to use rectangular objects or cylindrical objects

OpenStudy (anonymous):

yay

OpenStudy (anonymous):

For a prism, identify the length, width, and height. Use an appropriate unit of measure for measuring your object. Round all measures to the nearest whole number.

OpenStudy (anonymous):

the prism is the cereal box

OpenStudy (anonymous):

ok thank you so what measures are you going to have

OpenStudy (anonymous):

?

OpenStudy (anonymous):

ok im guessing you guys got it from here XD

OpenStudy (anonymous):

For a cylinder, identify the height and diameter of the base.

OpenStudy (anonymous):

um idk what numbers should i put

OpenStudy (anonymous):

for the prism the numbers will be 6,4,7

OpenStudy (anonymous):

@Chiko_1278

OpenStudy (anonymous):

sorry it thought anthony was going to help you

OpenStudy (anonymous):

i*

OpenStudy (anonymous):

for the cylinder 21, 10 , 6

OpenStudy (anonymous):

ok then............are you going to do diameter or radius on the cyinder

OpenStudy (anonymous):

?what

OpenStudy (anonymous):

yay hold on

OpenStudy (anonymous):

ok the area of the cylinder is 126 right

OpenStudy (anonymous):

oops i mean prism not cylinder

OpenStudy (anonymous):

you in 8th grade???

OpenStudy (anonymous):

7th

OpenStudy (anonymous):

i knew it

OpenStudy (anonymous):

you

OpenStudy (anonymous):

9th

OpenStudy (anonymous):

surface area was hard for me tho

OpenStudy (anonymous):

oh nice

OpenStudy (anonymous):

Determine the surface area of your object. Show all work and label your answer using the correct unit of measure. Determine the volume of your object. Show all work and label your answer using the correct unit of measure.

OpenStudy (anonymous):

i got the area of both allready so

OpenStudy (anonymous):

can you put the surface area formula down for me plz.......for both of them.and btw nice pic

OpenStudy (anonymous):

k sure

OpenStudy (anonymous):

Find surface area of rectangular prisms - LearnZillion

OpenStudy (anonymous):

go there

OpenStudy (anonymous):

just got to google and type in how to Find surface area of prism

OpenStudy (anonymous):

and you will see it

OpenStudy (anonymous):

aghhh im to lazy....

OpenStudy (anonymous):

lol

OpenStudy (anonymous):

just copy and paste my thing i wrote

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

you there

OpenStudy (anonymous):

this is how you find the surface area of a prism A=2πrh+2πr2

OpenStudy (anonymous):

i mean cylinder

OpenStudy (anonymous):

A=2πrh+2πr2

OpenStudy (anonymous):

dont do that and for rectangular prism is SA=ph+2b

OpenStudy (anonymous):

i said this is for cylinder A=2πrh+2πr2

OpenStudy (anonymous):

so find the perimeter and multiply it by the height and then find the base of the rectangle and multiply it by 2 and add what you got with the product of perimeter and height

OpenStudy (anonymous):

k so whats the surface area

OpenStudy (anonymous):

ohh so you want me to do the work.............bcz in os you can't give out answers you help ppl or else they will suspend me

OpenStudy (anonymous):

i can't find my calulater

OpenStudy (anonymous):

use the computer one then every computer has one

OpenStudy (anonymous):

@iambatman

OpenStudy (anonymous):

the surface area for the prism is 336 i think

OpenStudy (anonymous):

ok let me check

OpenStudy (anonymous):

the surface area for the cylinder is 420

OpenStudy (anonymous):

k

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

its right

OpenStudy (anonymous):

?

OpenStudy (anonymous):

ok just give me a min

OpenStudy (anonymous):

ok but i got to go soon so can you please try to do it fast
