A cylinders
The efficiency of packing of objects relies on the shape of the objects. There are two factors to take into account: empty space between objects (which cannot be avoided due to the object shape) and empty space around the outside of the objects and the packing container.

Is a cylinder!
Any solid object. 'Cuboid' means 'cube like'. A selection of cubic shapes is an house brick, a plank of wood,

Presumably they would be cylinders.
Orbits (of astronomical objects around other objects) are basically ellipses.
Aircraft fuselages, gun barrels, liquid storage tanks, steam boilers, water heaters, and the bodies of rockets are cylinders because this is the strongest elongated shape for containing internal pressure. The only shape that is stronger for containing internal pressure is the sphere. Drive shafts, revolver cylinders, and many other rotating objects are cylinders because this shape rotates easily. Ammunition cartridges are cylinders because they insert easily into the chamber in the gun barrel with little chance of catching and jamming due to their 360 degree rotational symmetry.
What objects have a hexagon shape?
Yes, objects with a streamlined shape experience less fluid friction compared to objects with a less aerodynamic shape. The streamlined shape helps in reducing drag by allowing the fluid to flow smoothly around the object, thereby minimizing resistance.

When it comes to recognizing engine notation. The letter means the formation in which cylinders are organized. The number means how many cylinders the engine has. V4= An engine with 4 cylinders organized in the shape of a V V6= An engine with 6 cylinders organized in the shape of a V
