A cube has 6 square faces o r sides. (Ref. Img 1) 2. A cube has 8 points (vertices). (Ref. Img 1) 3. A cube has 12 edges. (Ref. Img 1) 4. Only 3 sides are visible at a time (called "Joint Sides") and these joint sides can never be on opposite side to each other.   5. Things that are shaped like a cube are often referred to as ‘cubic’. 6. Most dice are cube shaped, featuring the numbers 1 to 6 on the different faces. 7.
