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.

OpenStudy (anonymous):

Did you understand?

OpenStudy (anonymous):

No Sorry >.<

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

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=?

OpenStudy (anonymous):

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.
