The top of a box might be a lid. If there is no lid, there may be flaps.
[despite the fact that this is under "rhetorical questions" I will answer it anyways] Man-holes are round because no matter which way you turn the lid, it will never fit into the round hole (With a slightly smaller diameter). If it were any other shape, like a square or triangle, it would be possible to drop the lid in the hole by turning it diagonally.
16 1/2 x 8 1/2 x 12 1/2 inches - with the lid on The lid ads about 1/4 inch on each side.
34 inches
It's the radius of a circle or sphere WITH A SHELL(or Thickness); like if an Lid on a jar had a diameter of 11mm across on the outside (top of lid); and was ONE mm thick, then the inside radius would be 5. ie; 11mm outer diameter, minus (-) 1mm thickness (aka; or shell) equals (=) 10mm (inner) diameter; which is a 5mm radius.
either a semisphere or a hemisphere
A rectangle is a two dimensional geometric shape and a pyramid and cube are three dimensional geometric shapes.These can be considered geometric shapes:A laptop with lid closedB a cardboard box with lidC piece of paperThese two would likely NOT have a geometric shape.D the inside of a plastic store bag full of purchasesE a flower petal?
Every object is 3 dimensional, no matter how flat they are!

A large soup kettle is called a stock pot.
A screwdriver used to pry off a lid on a paint can acts as a lever, specifically a wedge. The wedge shape of the screwdriver allows for the application of force to lift the lid.
The answer depends on what your unique shape is. Alternatively, just make a lid that is somewhat bigger than the terrarium and so sits comfortable to top of it.
