A modern house is not possible with low-quality and easily destructable building materials. But would you believe me if I told you that we analyzed a rather unusual building block? That building block is none other than the retail packaing of the brand new Xiaomi 15T Pro smartphone. Boasting a huge 6.83-inch screen and a 90W fast charger, this retail box is really considerable. A total number for a typical 100 square-meter apartment will surprise you.
Technical Analysis of the Xiaomi 15T Pro Retail Box
The Xiaomi 15T Pro comes in a box made of high-density rigid cardboard. Unlike the slim packs of the earlier models, this one has to hold a 90W Power Adapter and a bigger device. Its increased thickness allows for a stable stacking configuration resembling conventional bricks. These are intended for resisting vertical during international shipments, making high-density rigid cardboard a valid candidate material for constructing walls inside buildings.
| Dimension Parameter | Metric Value (Meters) | Description |
| Length (L) | 0.185 m | Accommodates the 6.83″ display |
| Width (W) | 0.095 m | Standard ergonomic width |
| Depth (D) | 0.065 m | Required for the 90W adapter |
To arrive at a needed quantity, a typical 100 square meter house, which has a ceiling of 2.8 meters, was chosen to calculate. With a “Double-Wythe” stack, its thickness would be 18.5 cm, which resembles a typical building brick. Calculations using mathematical modeling indicate that a whole building, from foundation to rooftop, needs units measured in tens of thousands.
- Exterior Walls: 15,417 boxes
- Interior Partitions: 12,243 boxes
- Foundation and Floor: 11,380 boxes
- Roof and Support System: 13,656 boxes
- Waterproofing Layers: 9,280 boxes
The cumulative requirement comes to around 64,610 units of Xiaomi 15T Pro boxes. Assuming an anticipated value of $800 for every device, the cost would easily surpass the $51 million mark. Although the cardboard material would provide a relatively good level of insulation, the stability would significantly depend on arid conditions, given the composition of cellulose.
