Is your cube a static mesh? As in not a BSP?
Depending on your workflow, your mesh can be already at the right scale for its usage (imported from Blender for instance), or you can use the texture coordinates on the UV map through the material editor (not advised imo), or change the UV mapping of the mesh (see the details panel of the instance of the mesh).
