๐Ÿ“– Your Story

You are a new detective at the Shape Detective Agency. Your chief, Inspector Geometric, has assigned you to solve cases involving mysterious 3D shapes. You must use your knowledge of faces, edges, vertices, and Euler's formula to sort shapes, find opposite faces, and complete your detective training.

What You'll Learn

  • Apply Euler's formula (F + V - E = 2) to verify properties of 3D shapes
  • Identify opposite and adjacent faces on cubes and dice
  • Sort 3D shapes by number of flat faces, curved faces, and edges
  • Understand why some shapes cannot exist (like a 3D shape with only 3 flat faces)

How to Play

1Examine each 3D shape carefully and count its faces, edges, and vertices (corners).
2Apply Euler's formula (F + V - E) to verify your counting is correct.
3Identify opposite and adjacent faces on cubes and dice by rotating them.
4Sort shapes into correct categories based on number of faces, edges, and other properties.
