Problem: How many cubic blocks does the fifth figure have?
Solution Guide:
- Count the number of cubic blocks in each figure to find the pattern.
- Use this pattern to determine the number of cubic blocks in the fifth figure.
Answer:
The first figure has 1 cubic block.
The second figure has 1 + 2 = 3 cubic blocks.
The third figure has 1 + 2 + 3 = 6 cubic blocks.
The fourth figure has 1 + 2 + 3 + 4 = 10 cubic blocks.
The number of cubic blocks in the fifth figure is 1 + 2 + 3 + 4 + 5 = 15 cubic blocks.
Challenge
