The volume of this cube is 1 cubic millimeter. What is the surface area of this cube?

If the volume of the cube is 1 cubic millimeter, then each side of the cube must be 1 millimeter in length (since volume = length x width x height).

To find the surface area of the cube, we need to add up the areas of all six faces. Each face has an area of 1 square millimeter (since each side is 1 millimeter in length), so the total surface area of the cube is:

6 x 1 square millimeter = 6 square millimeters

Therefore, the surface area of the cube is 6 square millimeters.
