Answer:
Length of one side = 3 millimeters
Step-by-step explanation:
I'm not sure what you mean by "r"
But you can find the dimensions of this cube.
The volume is length*width*height
In a cube, the length, width, and height are all equal in size.
This means that 27 is what length*width*height equals for this square.
So we can set up an equation.
27=x*x*x, where x is the length of a side.
Since 27 is a perfect cube root, we know that x=3.
So length of a side in this cube is equal to 3 millimeters.
Hope this helps!
