not to sound like a wise guy, but "cube" it

which is why we read \((.5)^3\) as "point five cubed" instead of "to the third power"

It makes no sense as presented. Please probide the EXACT problem statement and maybe throw in your efforts at a solution.

im doing a lab and i have the surface area but i dont know how to find the volume of it

satellite73Best ResponseYou've already chosen the best response.0
i was assuming the problem was "find the volume of a cube if the length of each edge is \(.5\)

Well, in your lab, they probably told you to use useful notation. I agree with this instruction. A cube cannot be "0.5 cm". The area of a side of a cube cannot be "0.5 cm". The length of an edge can be "0.5 cm". It would help everyone, especially you, if you would write more clearly exactly what it is you mean to convey. Sloppy language and sloppy notation kill people if you are building nuclear reactors. May as well start now learning how to be more careful and exact.

ikr? just compute \((.5)^3\)
 one year ago

tkhunnyBest ResponseYou've already chosen the best response.1
You're still doing it. It's volume. It cannot be "cm". You must think about what you are writing. You can't just guess. That doesn't work. You still have yet to confirm that satellite73's very resonable assumption about what you meant is, indeed, correct. Is the edge measurement 0.50 cm or isn't it? What did you get for the Surface Area?

my surface area is 1.25
 one year ago

HollisBest ResponseYou've already chosen the best response.0
and the edge measurement is 0.5

Awesome. No it's not. 1.25 is a number. You need some units. Is it 1.25 cm^2? That would be a proper designation if your arithmetic were correct. The edge measurement is not 0.5. That is a number. You need some units. 0.5 cm? That would be a proper designation. Edge: E = 0.5 cm Surface Area: 6*(0.5 cm)^2 = 1.50 cm^2 Volume: (0.5 cm)^3 = 0.125 cm^2 (this may need to be 0.13 cm^2, depending on your significant figure instructions.) No fooling  please learn to use proper units. Units are your friends. They will save youfrom many, many errors. It is NOT a small thing.
