Speaking of the warehouse rented by her childhood friend, it’s not a genuine warehouse but a room in an office building. The three rooms total a bit over one hundred square meters, which really isn’t large. The ceiling height of the office rooms here is low, about 2.5 meters, and the three forty-square-meter rooms have a total volume of over one hundred close to two hundred cubic meters.

The boys on the other side were once again surprised by these figures; they truly had no sense of numbers.

Xie Wanying explained to her classmates: Just because the overall space of the warehouse is large, it doesn’t mean it can hold that much stock.

You can’t just stack goods all the way to the ceiling, or else it would be too difficult for employees to retrieve items daily. The middle of the warehouse needs an aisle for people and handcarts to easily load and unload goods. Therefore, the space utilization rate of a warehouse is thirty to sixty percent, never one hundred percent.

Following this rule, moving all the goods into her childhood friend’s one-hundred-square-meter house wouldn’t be enough.

The usable living area in a house is already insufficient; the actual inside area of a so-called one-hundred-square-meter house is less than ninety. You need to subtract spaces like balconies, toilets, and kitchens, which cannot store goods; what’s left for stacking goods is only about fifty to sixty cubic meters.

In reality, even with her new house added in for storage, it would probably still be tight, and they’d have to stack boxes as high as possible to the ceiling.

Hearing her say this, Student Wei Shangquan said, "It shouldn’t be hard for my parents to find a warehouse for your friend to store goods. How big a warehouse do you think would be suitable, Yingying?"

"Let’s talk about vehicles first," Xie Wanying said, taking one step at a time; there was no need to rush or lose focus.

Wei Shangquan and the others followed her lead, realizing this classmate seemed like a know-it-all beyond just medicine; a whiz kid indeed.

"If a van doesn’t work, should we find a small truck?" Wei Shangquan asked.

Student Pan Shihua was the first to shake his head: "How big do you think a small truck can be? I see small trucks on the road, and their size is about the same as a mini-bus."

When it comes to everyday life capability, Student Pan’s cognitive ability was stronger than Student Shangquan’s, quickly adjusting his thinking.

Wei Shangquan recalled and wasn’t quite sure, so he asked Student Xie, "Yingying, how big is a small truck?"

"The small truck Pan mentioned should refer to a small box truck or a small flatbed truck. They belong to the light-duty trucks, with small tonnage and small loading volume, roughly seven cubic meters and six cubic meters, respectively. Flatbed trucks, which are open without box tops and walls, can’t actually load much. In reality, because it’s difficult to fix the height of the cargo, they carry even less than box trucks. Besides weight capacity, cargo transportation should also consider volume. For regular-shaped items like this, a box truck is best for loading. For irregular-shaped ones, a flatbed truck has more advantages."

Hearing this, it seemed light-duty trucks wouldn’t work, so Student Wei Shangquan asked again, "What about a medium truck? Should we use a large truck?"

The more the classmates asked, the less confidence they had in their own sense of numbers, thinking they might as well go with the biggest truck to be sure it could fit everything.

Once again, they faced a professional critique from Student Xie.

"It’s not about getting the biggest truck possible. Not mentioning the transportation costs, you must understand, vehicles need to comply with city traffic regulations when operating. Trucks are prohibited from entering the city during the day; some tonnage vehicles are allowed into the city only at night, which means loading and unloading can only happen at night. Poor night lighting limits drivers’ visibility, and larger tonnage trucks have trouble making turns at night, wasting time and easily causing accidents. The last time I checked a traffic sign, it seemed the Capital only allows trucks below eight tons to enter the city at night for loading and unloading, unless they’re special vehicles."
