Um... the OP has made a slight mistake if he is trying to ask the same question as the one off the telly...

there are 3 wheels of cheese, of equal thickness.
the first has a diameter of 12 cm
the second a diameter of 16 cm
and the last one a diameter of 20 cm

Cut the three cheeses up in as few cuts as possible so that there are 4 equal portions of cheese.

So the OP completely fcuked up the question?

Line them up, make one cut through them all. Now you have six pieces. Rotate each cheese 90 degrees and repeat. Now you have 12 pieces. Make 4 piles of cheese with a quarter from each cheese.

You're going to need a big knife. Probably bigger than Crocodile Dundee's.

you cant combine 4 and 8 to make 12 with cheese.
Its not 4 equal pieces its six pieces

Put the 12m2 cheese on top of the 16m2 cheese and cut around it. You now have two 12m2 cheeses and some left overs. Do the same with the 20m2 cheese. You now have three 12m2 cheeses and leftovers that add up to 12m2.
Enjoy with a nice bottle of wine from the cellar.

It says divide evenly, not make equal-sized pieces.

Ok, I saw this on TV a few days ago and thought I would ask you guys if you can figure it out. I know the answer by the way.

You have 3 circular blocks of cheese. One 12m^2, another 16m^2 and the final one 20m^2. You cannot stack them on top of each other. How can you divide them equally into 4 with none left over? It can be done in two cuts.

It's clever too!

Easy. Combine them, then make two cuts to divide them into 4 equal pieces. That's too easy actually, so what's the answer?

Don't know if it's been solved yet but here goes:

Cut the 16m^2 into 4 quarters.

The 2 cuts would length-ways and breath-ways (not sure if that makes sense but if you look at it top down it would be north to south and west to east).

Now you have 4x4m^2 (16m^2)

Take one of those and put it with the 20m^2 = 24m^2.

Then put the other 3 (3x4m^2= 12m^2) with the 12m^2 = 24m^2.

Or cut off 4m2 from the 16m2 then add it to the 20m2 = 24m2 then cut in two. There's a few ways to do it i guess.

i love the fact the op has tricked After Hours into doing math!

also watch the new season of this to see the answer!
