    Answer:
Material Economy: round shape requires less surface area per volume and thus reduces the materials needed.

Produce Efficient: round shape cans are easier to make and they roll off the assembly line easier then the square ones.

Pressure Resistance: round shape does not have corners to dent. The curved surfaces are more resistant to denting or pressure, especially for soda and beer cans with increased inside pressure.

Can Opener: can opener is easy to operate continuously on a round can.

Holding Comfort: it makes you feel better and more confortable holding a round can than a square one.
