Question

**Title: Understanding Block Stacking with a Pyramid Diagram**

**Introduction:**

This section will explore how to determine the number of blocks needed to construct a pyramid-like stack when the bottom row contains a specific number of blocks.

**Problem Statement:**

How many blocks would be needed to build a stack like the one shown in the figure if the bottom row has 21 blocks?

**Pyramid Construction:**

In the diagram, a three-dimensional pyramid is represented, where each subsequent row has one less block than the row below it. The bottom row consists of 21 blocks.

**Concept Explanation:**

The pyramid is structured so that each level of the stack reduces by one block from the previous level. For example, if the bottom row is 21 blocks, the next row will have 20, then 19, and so on, until the topmost row, which consists of only 1 block.

**Calculating Total Blocks:**

To find the total number of blocks, you will add up the blocks from all the rows:
- Bottom row: 21 blocks
- Second row: 20 blocks
- Third row: 19 blocks
- Continue this sequence until the top row.

The sum of the sequence is the addition of all numbers from 1 to 21. This can be calculated using the formula for the sum of an arithmetic series:

\[ \text{Sum} = \frac{n(n+1)}{2} \]

where $ n $ is the total number of blocks in the bottom row.

**Need Help?**

Click "Read It" for additional details and step-by-step guidance on calculating the total number of blocks.

**Conclusion:**

This exercise helps to understand the arithmetic sequence and its application in calculating totals in structured stacking scenarios.
