Make it infinitesimally small.
It makes it easier to put the boxes into outers for shipment (the outer will also be a cuboid and will have an exact number of cereal packets in it without any wasted space, and the cuboid outer is easier to stack for transportation);The cuboid cereal packets stack easier on the shop shelf;The cuboid cereal packets stack easier in the cuboid cupboards of [most] houses.
A cuboid is 100% of a cuboid and 0% of any other shape.
The concept of a perimeter does not make sense for a solid object.
A cuboid is shaped like a cube. Which could be a rectangular shape, like a shoe box, or cornflake packet. So any box would make a model of a cuboid.

You would need 12 straws because a cuboid has 12 edges, 8 vertices and 6 faces

A cuboid is 100% of a cuboid and 0% of any other shape.
