Express the surface area of a cube

Click For Summary
SUMMARY

The discussion focuses on expressing the surface area of a cube as a function of its volume. The volume of a cube is defined by the equation V = L^3, where L is the length of a side. To find the surface area, represented by A = 6L^2, the length L can be expressed in terms of volume as L = V^(1/3). Substituting this into the surface area formula yields A = 6(V^(1/3))^2, simplifying to A = 6V^(2/3).

PREREQUISITES
  • Understanding of basic geometry concepts, specifically cubes.

Homework Statement


Express the surface area of a cube as a function of its volume.


Homework Equations


Cubic Volume=Length x Width x Height (V=Length of side^3)
Cubic Surface Area= (Length of side^2)x6

The Attempt at a Solution


f(V)=(X^3/X) x 6...sorry, I don't know if I'm on the right track, as there are no given examples similar to this in my text.

Maybe solve V=L^3 for L in terms of V and then substitute into A=6*L^2?
