Answer:
Part A) The length, the width and the height have the same value equal to [tex]3\ ft[/tex]
Part B) [tex]27=x^{3}[/tex]
Step-by-step explanation:
we know that
The volume of a cube is equal to
[tex]V=x^{3}[/tex]
where
x is the side length of the cube
Remember that in a cube the length, the width and the height have the same value
so
in this problem we have
[tex]V=27\ ft^{3}[/tex]
substitute
[tex]27=x^{3}[/tex]
[tex]x=\sqrt[3]{27}=3\ ft[/tex]
