B). It measures the amount of something the covers a 3-dimensional object such as paint,wrapping paper,or fabric.
C). Can be calculated by adding the areas of the individual faces of any 3-dimensional shape.

Answer 6

It is supposed too say net* but i don’t know what net means either lol 😂 🤷‍♀️

Cool, thanks, I never heard that terminology before. Too old I guess.

Answer 8

That link I posted tells you what the nets are.

Answer 9

( The shape of all surfaces of the object projected on to the same plane.)

Answer 10

By the way we ship designers have a term called "developable surface". It is a surface that only bends in one direction at a time, so you could build it out of plywood for example. If it curves in two directions at once like most ship hull shapes, plywood for example would not work (try it with cardboard.) It would be hard to do the "net " thing with a ship hull :)

Answer 11

Notice for example that a sphere is not included in the examples given in that math link :)
