Question 831775: Hi There,
I want to bake a BIG BIRTHDAY CAKE in the shape of a rectangle. The problem is how much flour do we use to bake a cake that is 2m in length, 1m in width and 0,5m in width? How many KG's of flour are required?
Thanks,

Is this a algebra question or a baking question?
If you use a 2x1x0.5 m pan to bake a cake, you can't calculate the volume of flour I need based on the pan (V=2x1x0.5) because a cake is made of flour, eggs, butter, etc. and also there are a lot of air bubbles that make a cake light and eatable (if that's a word). Also, you need the density of the flour to calculate the mass of flour need using the equation,
M=rho%2AV where rho is the density. Also a 0.5m thick cake will probably be raw in the middle when the edges and the top start to burn.
Make thinner cakes and then stack (layer) them together.
