Have you ever come across a puzzle that seems simple at first but gets trickier the more you think about it? That’s exactly the case with the viral image of a tiled floor where a cross-shaped section is missing. The question is straightforward: How many tiles do you need to complete the floor? The given options are 12, 13, 9, or 10. Let’s dive into the reasoning and find the correct answer!

Understanding the Puzzle: A Visual Conundrum

The image shows a beautifully tiled floor with a peculiar gap right in the middle. This gap takes on a cross-like shape, adding a bit of a challenge to calculating the number of missing tiles. At first glance, the gap may appear confusing, but with a strategic approach, the answer becomes clear.

To make it more understandable, a second image shows the same floor with a red grid drawn over the missing section. This grid perfectly divides the cross-shaped area into square tiles. By carefully counting the grid squares, we can determine the exact number of tiles needed.

The Shape of the Missing Area: A Cross in Disguise

The missing section is not just a random gap; it forms a symmetrical cross. To analyze it correctly, we must break down the cross into smaller sections that align with the tile pattern on the rest of the floor.

The cross-shaped gap consists of:

• A central square tile in the middle.
• Four arms extending outward from the center, each arm consisting of multiple squares.

Counting the Missing Tiles: Why the Grid Matters

Thanks to the second image with the red grid, the calculation becomes crystal clear. The grid outlines the missing tiles in a way that allows us to count them individually without any confusion. This visual aid is crucial because the cross shape can easily lead to miscalculations when relying solely on the first image.

Breaking Down the Tile Count

The red grid clearly shows that the cross shape is divided into 12 square tiles. Here’s how it breaks down:

• The central part of the cross contains 1 tile.
• Each of the four arms contains 2 tiles (one tile next to the center and one extending outward).
• In addition to these arm tiles, there are corner tiles that complete the cross shape.

Therefore, the calculation is as follows:

• Central tile: 1
• Four arms (2 tiles each): 4 × 2 = 8
• Corner tiles: 3
• Total tiles: 1 + 8 + 3 = 12

Why 12 is the Correct Answer

The reason why many might guess incorrectly lies in the illusion created by the cross shape. It appears irregular at first glance, but the red grid helps eliminate any ambiguity. Once the area is broken down into square tiles, it becomes evident that 12 tiles are required to fill the missing space. Therefore, the correct answer is 12 (option A).

Why Did Some People Get It Wrong?

Many people who guessed 9 or 10 likely based their answer on visual perception rather than careful counting. The brain tends to simplify complex shapes, especially when they form a pattern like a cross. Without the grid overlay, it’s easy to overlook some of the smaller sections, leading to an incorrect guess.

The Power of Visualization in Problem-Solving

This puzzle is a classic example of how visualization can transform our understanding. By drawing the red grid on the missing section, the problem becomes manageable and straightforward. It teaches us that sometimes, taking a different perspective can reveal the solution to what initially seems like a complex problem.

Final Thoughts: Always Double-

In problem-solving, especially with visual puzzles, our perception can sometimes mislead us. Taking a step back and using tools like grids can help break down complicated shapes into simpler components. In this case, the seemingly tricky cross-shaped gap on the tiled floor turns out to require exactly 12 tiles to
