Question 86100
The volume of cube can be found using this formula:


{{{s^3=V}}} where s is the length of the side and V is the volume


So if we know the volume is 27, this means V=27


{{{s^3=27}}} Plug in V=27



{{{root(3,s^3)=root(3,27)}}} Take the cube root of both sides  (this undoes the exponent)




{{{s=3}}} Use your calculator to evaluate the cube root of 27


So the length of the side is 3 feet. Now lets count the number of segments. There are 12 segments that form the cube. So if we multiply 12 by 3 we'll get the total perimeter of the cube. It turns out that the perimeter of a cube is 


{{{P=12s}}}


{{{P=12(3)}}}


{{{P=36}}}


So the perimeter of the cube is 36. So the answer is B)
