Hi everyone,
I had a bride ask me to do her cake but she wanted to cut the main cake into 3 x 3 slices to give to her guests as they leave. How would I figure that out? Like how much cake would I need she is wanting square cake. How much cake should we make? Ahhhhh I have never ran across this before Can someone help???? Thanks gals and guys.
oddly, that's the exact size of a post-it note...but 4" high...wow, that's a big chunk of cake!
She can serve them whatever size she wants but I would charge $x.xx per serving size of 1x2x4. She's going to need a lot of cake.
That's a lot of cake indeed.
1x2x4 = 8 cubic inches of cake
3x3x4 = 36 cubic inches of cake
36 divided by 8 = 4.5 so she would need 4.5 "servings" per guest.
WOW!! 
absolutely!
I remember they used to do that a lot in weddings. Give the guests a piece of cake as a favor. That's gonna be expensive.
But not a piece that big! 
Is she thinking of a one-layer sheet cake? I'll bet she just has no idea of how big that piece would be.
Sorry everyone,
I had customers so I almost forgot about this cake box drama.. lol
Now she has written back and decided on a flat box dimensions are
4 9/16 x 3 9/16 x 1 1/4 thick so a little less cake but not by much.
So what do you think we need enough cake for 120 ppl. we were thinking about a 6 - 8 - 12" square should feed 140 with normal slices not sure with the larger pieces. What do you all think? Thanks again for helping
That makes more sense, you'd be cutting pieces that were 1"x2"xheight of the cake, which would fit flat in that box with a little room all around. If you cut them that size and have 6-8-12 squares that would give you 122 servings.
