What else can I help you with?
What us the top of a box called?
The top of a box might be a lid. If there is no lid, there may be flaps.
Why is it that the man-hole is round?
[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.
What are the dimensions for a box of copy paper?
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.
what- use a formula to find the perimeter of the square box lid in inches.?
34 inches
What do you mean by internal radius?
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.
