true
You can imagine any 3 dimensional shape as stacking the 2 dimensional version of that shape on top of each other.
Actually, it is false.
You can imagine a 3-d object being made up of a lot of 2-d objects stacked on top of one another. But remember that, by definition, a 2-d object has no thickness (or, in this case, height).
Height of one 2-d obect = 0
so height of n such objects = n*0 = 0
So a stack, no matter how many objects you use, will remain 0. And so you are not building up a 3-d object.
Alternatively, you could imagine a cube (3-d) being built up from 6 square faces (2-d). Except that this is just the shell of the 3-d object, not the 3-d object itself.

That's more of a statement than a question. It's also a false statement. You can build a three dimensional object from two dimensional objects, if you have an infinite number of them.

not really because they are 2 diffrent objects floor and stair hall is only BUILT on the floor witch makes it no.
Built up area is the area which has been developed.and floor area is the area which is about to built or about to develope.
