Question: A futuristic city has $ 325 $ floating platforms arranged in a perfect cube grid. If each platform is a square of side length $ 4 $ meters and they are arranged with a $ 1 $-meter gap between adjacent platforms, what is the total area, in square meters, occupied by the platforms?

**What Defines the Future of Urban Living—Floating Platform Cities?**
As cities grow denser and coastal risks rise, futuristic urban concepts are capturing attention worldwide. A striking example is a conceptual floating city built from 325 cube-shaped platforms, each 4 meters on a side, spaced with 1-meter gaps. These modular platforms float above water, reimagining how humanity may develop beyond traditional land limits. With increasing focus on climate adaptation and smart infrastructure, such designs merge cutting-edge engineering with sustainable spatial planning—raising natural questions about real-world footprints. **Why This Question Is Gaining Traction in the US**
Across the United States, themes like modular living, climate resilience, and innovative architecture are top of mind. This cube-gridded floating platform model aligns with emerging trends in adaptive urban design and floating infrastructure prototypes. With rising sea levels threatening coastal communities, interest in above-water living solutions is growing. As digital and print platforms highlight sustainable innovation, this question reflects public curiosity about scalable, futuristic housing models that blend utility and vision. **How the Platform Grid Actually Works: A Clear Breakdown**
The cube grid organizes 325 platforms in a perfect cube formation. A cube number matches the root: ∛325 ≈ 6.87, so the closest integer cube grid is 7×7×7—totaling 343 platforms. Because only 325 are built, the layout accounts for a 12×12×12 cube footprint (54m × 54m × 54m base), with 18 unoccupied positions distributed uniformly. Each platform spans 4 meters per side, forming a square. Adding a 1-meter gap between adjacent units ensures structural stability and access clearance. Economically, this layout maximizes usable space while reducing environmental disruption—ideal for floating foundations above sensitive coastal zones.
