Soup cans > soup cubes

I was wondering why they make them in cans rather than cubes since it’s space lost and found this:

The cylindrical shapes of cans are a major benefit when manufacturing products. The cylindrical shape is the perfect cross-section of using the least amount of material but being able to fit the most product into shipment boxes and on store shelves. A spherical shape is inefficient for packaging, and a cubical shape is inefficient in terms of material use. The cylindrical shape is just right by using a rounded top (like a sphere) and elongated sides (like a cube). This cylindrical shape is also critical for withstanding pressure. This shape can withstand up to 90 lbs of pressure, making them a durable product for day-to-day life.
