How to make your cake and size you want.....

Have as big a size as you want...

Ok so you don't want a piece the same size as mine.

Here is how to make the cake any size you want.

First this will still be 8 pieces if you make the cake.

To make to tops.

Start with a square and size you want.

The only important measurement here is

the side of your square.

We will call this A  
 For tab, say you used 1cm wide....

So if my square was 20cm by 20cm
half this is 10cm.

A would be 10cm - 1cm =9cm

so A= 9cm

and you said you would never use algebra..

Repeat making you tops exactly as in this picture.

To make the side of the slice.

Decide how much depth you want for the cake.

I made my tabs quiet fat at 2cm wide but you can make them skinnier, at 1cm..

If you were making a smaller cake 

you could do 7.5 cm wide.

and score at 1 cm for tabs, this would mean you got 4 slices from a sheet of scrapbook card stock.

and your cake would be 5.5cm thick as you need a tab top and bottom..

This is where you need the A..

to find out how long a piece you need

Just do 3 times A plus 3cm

Or measure roughly round all the sides of the triangle and add 3 cm for the tab .

A bigger tab means it stays closed.

Yes it is that easy

Score your card at A and 2A.

so mine is at 9cm and 18cm.

We don't need to score the lid till we stick the slice together.. 

So when you have made the slice and you fold it over you then find out where you need to score

 for the tab.

Make Sure you tab is shorter than 
the A measurement.

OR the box won't close,

so you can cut as much as you like off too make the tab look neat, but please leave about 3cm as I said, or the tab may jump out then it's closed.

You don't want a cake with 8 pieces..

If you don't want to make this many it's easy to make it your size.

Take a piece of scrap paper the same size as you want to make your cake...
it needs to be a Square

Mark the center of the paper,  cut down to center.  

Now fold the paper over until you have as many slices as you want for your cake, 
don't cut it just fold like a fan ..
Yes bits may stick out, but you can keep making you section larger or smaller till you have equal folds.
This way you can have as many slices as you want.

Now cut one section off.
Yes it may seem a funny shape. 
But all you really need is that it has the point at the center. 
This is your template

To make your slice tops...

Remember to take half the size of your card and take 1cm off to get your A length.

You need to put both pieces of card together.
If your going to make 5 pieces 
put 5 paper clips around you square 
at equal distances. 

YOU NEED TO DO THIS AS YOUR GOING TO WANT A TOP AND BOTTOM 
some of the pieces may be a tiny different in size, this really doesn't matter so long as you use the pairs held by the paperclip.
Also since it has all been cut from a whole square
 it will always fit to make a cake.

Mark the center of the card and with the 2 pieces of Square card together, cut down to this point....

Lay your template next to the cut line 
point towards the center, 
move your paper clip if you need too.
Cut along the edge of the Template.
Repeat till all your slices are cut.

Now you just repeat as before. 
From the previous Tutorial...
Either flip the top piece over 
or measure from the point.

have fun.
