I do not want to fail this, could you please help me with number 1 and 3.D, and then check my other answers? Thank you.
1. Find and simplify the volume-to-surface-area ratio for each of the three possible ice cube shapes. You can use this chart.
|Shape| S/A Formula|Volume Formula
Cube | S.A=6s^2 | V=s^3
Sphere|S.A+4 pi r^2|V=4/3 pi r^3
Cylinder| S.A=2 pi r^2+2 pi rh |V= pi r^2 h
2. Use the ratios to choose the best shape for an ice cube—a cube, sphere, or cylinder. Also, choose what you think is the best size for that shaped ice cube.
I would say a cube would be best for an ice shape.
3. Consider these questions as you make your decision:
a. Since the purpose of an ice cube is to keep a drink cold, is it better for an ice cube to have a high volume or a low volume?
Low volume?
b. Since heat touching the surface of an ice cube causes it to melt, is it better for an ice cube to have a large surface area or a small surface area?
Large surface area?
c. Which volume-to-surface-area ratio would be better for an ice cube— the lowest possible or the highest possible?
Lowest Possible?
d. How does increasing the size of an object affect its volume-to-surfacearea ratio?
??
4. Create a visual model to show your ice cube design, including the dimensions you would choose and the volume and surface area of that cube.
No one told you to copy😂😂
#1 just divide volume by area. For the cube, that's
v/a = s^3 / 6s^2 = s/6
#2. You're just guessing, if you haven't answered #1. And what is the "best" shape for the ice solid? I assume you want to use the least material to get a desired volume. So, you need to find the maximum v/a ratio.
#3 (a) to keep the drink cold, you want the ice to last as long as possible. That means exposing the least surface area.
(b) to chill the drink fast, you would want larger surface exposure. To maintain some cooling longer, low area.
(c) depends on your goal, as noted in (b)
(d) Note that in every case, the ratio includes a factor of size. The larger the volume, the larger the ratio.
#4. by the time you have considered the other parts, done some googling of the questions, this should not be too much of a challenge.
I know right like me here it 2021 in quarantine just sick of school and giving up so doing the whole project from Jishka and Brainly
yah same here i could car else about school i barley care about starting highschool next year
ik its been 5 years but what did you get on the test.. xD
ummm sock
I THINK IT WAS HELPFUL
This helped me a little.. thanks
This was helpful! Thanks :)
um which is the best shape cuz i tried to do all the calculations using 3 for side, radius, and height and now idk which one to choose
cube ratio = 1 : 3
sphere ratio = 17 : 25
cylinder ratio = 1 : 2
like idk if the volume for the ice should be high or low like what are the benefits?????
