Question

Find a function that models the surface area S of a cube in terms of its volume V
(On my webassign account i put the answer 6v^(2/3) and it says its wrong)

Answer 1

I'm getting the same thing.


V = volume
s = side length
SA = surface area



V = s^3

s = V^(1/3)

SA = 6s^2

SA = 6(V^(1/3))^2

SA = 6V^((1/3)*2)

SA = 6V^(2/3)

Answer 2

so there's probably a glitch somewhere

Answer 3

or you could try using a cube instead of the fraction exponent

Answer 4

Thank you, you were right the website is really strict and i put in 6v^(2/3) when i should have put 6V^(2/3) thanks.

Answer 5

oh something silly like that? how lame

but I'm glad you figured it out
