Get your brain working! STEM puzzle challenge: improve thinking skills and maintain brain activity.

Recently, in order toExcellence CupTo reinforce the three-dimensional concept of the Little Tycoon game, I bought him some Amazing Cubes to play with.

Introduction to Yusile Cube

Yusile Cubes is a STEM creative game where each cube is approximately 2 cm on each side, a size suitable for children to handle. By rotating the cubes to different faces, children develop logical thinking, hand-eye coordination, and 3D spatial awareness. It can inspire children's concentration and creativity, making it a great board game option when it rains and they can't go out.

How to play the Yusile Cube:

• Use the same shapes to create a specific target
  • Typically, they are cubes with the same side length, such as 3x3x3 or 4x4x4.
• Soma Cube
  • 3D Tangram

Construct a 3x3x3 cube using the same pattern.

Question 1: Using the following combinations, stack a 3x3x3 cube.

• 2x2 square blocks – 6
• 1x1x1 cubes – 3
• Difficulty: Easy

solution:

Steps 1-2:

The image on the left below is an incorrect example because there are only three 1x1x1 "white" blocks, which shouldn't be wasted. Therefore, it should be changed to the image on the right below, swapping the "white" and "brown" blocks to reduce wasted 1x1x1 blocks.

Steps 3-4:

Next, push the second layer forward, place the "white" cube in the middle, and you're done!

Question 2: Using the following combinations, stack a 3x3x3 cube.

• Z (lightning bolt) shaped blocks – 6
• 1x1x1 cubes – 3
• Difficulty: Medium

solution:

Steps 1-2:

The following steps are an incorrect start. The two Z-shaped blocks cannot be placed flat, because no matter how they are placed, one side will always have more than 3 blocks.

Step 3:

Use the "white" blocks to fill the corners of the first layer, and then stack them up to complete the first layer.

Steps 4-5:

Why not place the "coffee-colored" Z-shaped blocks horizontally in the middle of the second layer? It's because if they were placed in the middle, the third layer would be split in two and become broken, causing the "orange" Z-shaped blocks to exceed the range of 3 blocks.

Step 6:

Place a "white" block in the middle of the second layer.

Steps 7-8:

Place the remaining Z-shaped blocks in the empty spaces to complete the task!
