Question

What is the surface area of
0.5 cm
1.0 cm
1.5 cm
2.0 cm
Thanks :)

Answer 1

ques is nt complete

Answer 2

Is there a picture to follow cent? :D

Answer 3

No its for a school project and you had to cut an egg into four cubes and the measurements of the cubes are supposed to be those above.

Answer 4

So you cut an egg into 4 cubes, and widdled the smallest cube down to a size of .5 on each side.
And did the same for the other measurements i guess..? :X
And so the problem is, find the surface area of each cube with the given side length? :D

Answer 5

Yeah sorry I forgot to put that :) And then it has this its a chart and this is the part I need to fill out. Surface Area (cm2)
(Side x Side x 6)

Answer 6

Hmm well if it's a cube, then each of it's sides are suppose to have the SAME measure as one another.
So if one side is 0.5cm, then the length, and width of that particular cube will be 0.5cm also! :D

\[\large (0.5cm \times 0.5cm \times 6) = 1.5cm^2\]
So this is what the first one would look like, understand? :D

Answer 7

Yup thanks so much. For the next one it would be (1.0cm X 1.0cm X 6) = 6?

Answer 8

Yah looks good :)

Answer 9

You're multiplying centimeters and centimeters, so you should end up with square centimeters for your units, not a big deal, but your teacher might want to see the units ^^ (Unless it's labeled on your chart already) :D

Answer 10

Fabulous thanks so much:)

Answer 11

Ah im sorry could you help me with one more?

Answer 12

sup :D

Answer 13

Alright so this is the next part of the chart. We need to find the Volume (cm3)
(side x side x side). Would we just do 0.5 X 3 = 1.5cm^3?

Answer 14

No not quite,
\[(0.5cm \times 0.5cm \times 0.5cm) \neq (0.5cm \times 3)\]
Don't use the 3 :D Use the equation on the left.

Answer 15

0.375cm?

Answer 16

Lol sorry im confused

Answer 17

0.125cm3

Answer 18

If (side)=0.5cm
then,\[\large (side \times side \times side)=(0.5cm \times 0.5cm \times 0.5cm)=?\]

Answer 19

Yah i think thats right c: gj

Answer 20

Thanks :) And then I have one more part of the chart. Are you up for it?

Answer 21

LOL XD I dunno, just post it :3 i'll see what i can do

Answer 22

Alright last one thanks soo much. Surface Area to Volume Ratio
(surface area/vol.)

Answer 23

Do I just divide Surface Area to the Volume Ratio?

Answer 24

Hmmmm yah that sounds right :D
What'd you get for the 0.5cm cube?

Answer 25

When I divided 0.5/0.125 I got 12 then do I divide the the 2cm and the 3cm?

Answer 26

You divided 1.5/0.125, and got 12 :D
(surface area/volume) Hmm yah that looks right.
I guess that tells us the ratio of the surface area to the volume.
The tiny 0.5cm cube has 12 times as much surface area as it does volume.

Answer 27

Do I just put 12 or do I divide the cm part like the 2cm and the 3cm?

Answer 28

Hmmmm good question.
\[(\frac{ 1.5cm^2 }{ 0.125cm^3 })=\frac{ 12 }{ cm }\]
Hmm that's kind of awkward looking :O The surface area is 12 units larger than the volume per centimeter, .. i guess? :3 hmm sorry i dunno on that part :D mind blanking.

Answer 29

Aha it's alright. I'll just go with putting 12. Thanks so much :o)
