Anyone knows how to do this? PLEASE! and thank you so much in advance . Designer to be : You were invited by a certain company, owner challenge you to produce a solid figure by following the suggested surface area.You are to present your output to your classmates and to your teacher. Write the corrseponding formula in computing for the surface area and prove that the surface area is quadrant in nature. Please give me the exact formula, or anything you know about it. Thanks!

    you are asking for a formula, that gives you the surface area of some 3d figure, and the formula is quadratic? is that what you are asking for?

    @vipul92 we're actually gonna make a figure of it. so what's that figure?

    then that could be alot of things, a sphere, cylinder, a cube, there are many formulas that are quadratic

    well like a said there are many formulas that are quadratic, it sounds like you can use any of them. but a cone is one yes.

    for you which is the simpliest formula? @zonazoo

    a cube is the easiest... 6s^2, where s is the length of the side.

    so our teacher told us to give an explanation about that question as stated above. i don't really know how to explain or report it. u know. so if i'm using cube, how am i going to report it in front of our class?

    well still, it doesnt really make sense to me what you are asking. its says the company challenges you to produce a solid figure with the suggested surface area... but there isn't any given... so how are you suppose to know what type of shape or size or figure that they even want... there are different types of shapes that are quadratic with surface area... and there is no need to prove this, because surface area is 2 dimensional, and is to the second degree, meaning all the formulas are in the form Ax^2+bx+c, so honestly I don't know what they are asking for.

    My classmates were makign a cube, almost all of them. So now any idea?

    well if they don't give you any specific measurements for the surface area they want, then why dont you just make a graph, with the length of the sides as the x axis and the surface area as the y axis, and you will see that once it is graphed it is quadratic

    my mates told me that their formula is = 6a squared.

    yes that is the formula for surface area of a cube

    Now I get it. Last few questions : What if my teacher will ask me if how did I get cube? And explain how & why cube? What if she's going to ask me that?

    well its a cube b/c that is what you decided to use... you didnt have to choose a cube, but it is the easiest and clearest, because you can see it is in the form ax^2+bx+c, and since the b and c of this equation are zero, you are left with ax^2, and the formula for a cube is 6x^2, so the a=6, you can graph this and show that it is quadratic, but again, you could use almost any formula for surface area and show this same thing.
