Identify Cubes

🧊 A perfect box! A cube is a 3D shape that is perfectly identical on every single side.

Lesson 6

Concept

A square is flat, like a piece of paper. A **CUBE** pops out at you like a cardboard box! šŸŽÆ **The Cube Rules:** 1. It is a 3D shape (it takes up space). 2. It has exactly **6 sides**. 3. Every single side is a perfect Square! (Wait, is a brick a cube? NO! A brick has long rectangle sides. A cube cannot have any long sides. It must be perfectly equal everywhere you look at it!).

Try it

Find the perfect box! **Instructions:** Figure out if the real world object is a real Cube or not! **Problem 1:** You see a picture of a regular 6-sided Dice (the kind you roll for board games). * Does it have 6 perfectly square sides? (Yes/No) * Is it a Cube? (Yes/No) **Problem 2:** You see a picture of a cereal box. * The sides are very long rectangles. * Is it a Cube? (Yes/No) **Problem 3:** You see a picture of an ice cube from the freezer. It melted a little and looks lopsided. * Math cubes must be perfect. If it's lopsided, is it a math cube? * Answer: (Yes/No)
