Well the area of a cube is a*a*a where a is a side length
OpenStudy (anonymous):
In this case the area of the cube is a^3=2744 (a^3 because a*a*a=a^3)
OpenStudy (anonymous):
Given this can you figure out what a is equal to?
Remember a=the side length of the cube.

No Sorry >.<

so a^3 is the volume of the cube. a is the side length. We need to solve for a.
Since 2744 is the volume of the cube we can set up the equation a^3=2744
OpenStudy (anonymous):
Do you understand? If you don't tell me which part you don't understand.

How Do I Figure Out What A Equals To? What Number Is A?
OpenStudy (anonymous):
solve for a by taking the cuberoot of 2744.
so we have a^3=2744
then you take the cuberoot of 2744 and you are left with:
a=?

Will It Be 14?
OpenStudy (anonymous):
Yeah but since that isn't a choice you have to go with the unsimplified version: cbrt(2744) or D.
