Calculus with a daily problem

And is that - see you gonna do a cake that is 2 recepies but this is not the calculus, is because for most of teh people that work with cake the basic recepi is the size of a coffe cake or one that full one medium pan, 

So the calculus is that you don't know what is better do a higher cake that is thin or a short cake that is larger, you want to know wich cake would take more cake icing, 

You gonna be in the right direction if you think that way for the calculus of the doug you gonna use volum, with 2 cakes recepies you fill 2 pans of medium size but with the same 2 recepies you fill how much small pans? Acording the size of your kitchen pan, so you gonna have to measure the base of the pan, and I gonna say for you the high of the cake before bake(have the growth) but see when you are n a kitchen you can't fill to much the pan or you can have not expected bake (in the middle is not cook) with the growth the cake pull out and is in all the oven so that you don't gonna think about is given in the problem.

And to calculate the cake icing you gonna use area, because yuo know that ne recepie that you do for the lower cake cover, but you aren't sure is the high one covers, is volum but you see the hight of the icing is 3mm and you are comparing, no matters the size of the cake the hight of the icing never gonna be different of 3mm, so is area if one are two times of the area of the other you gonna double the recipe no matters the

 3mm of height. Rute Bezerra de Menezes Gondim
