I've never read/watched it! How am I supposed to know? Is the answer three?! Two?!

You know, I'm just going to think of a complicated balancing equations problem to put here and that way you actually have to think to answer it. Either that, or I'll put up a National MathCounts problem. *meh*

I guess I will give a hint.

Since no one gets the question, this topic should be locked. (I don't mean this seriously, it's the hint)

What is the hint?

I searched it up and it said four stinking kids and a dog. It says so on Wikipedia.

Did it say four STINKING kids and a dog?

No...I looked it up on Wikipedia too...

What did it say?

Julian, Dick and Anne get together with their cousin George

Four Children! Count them!

That right! it's four with a dog, that's why it's called Blytons Famous Five.

Well, count the dog.

It will be five. But the dog is not a kid!

Now the answer would be FIVE then, wouldn't it? But last time I checked, DOGS WEREN'T CONSIDERED CHILDREN!

You are right dogs are not considered children.


Girls turn :grin:!

Let's see, um, something nice and hard... Looks in MathCounts National Problems.

(an easier one to start with)

Two regular square pyramids have all edges 12cm in length. The pyramids have parallel bases and parallel edges, and each has a vertex at the center of the other pyramid's base. What is the total number of cubic centimeters in the volume of the intersection of the two pyramids? Express the answer in simplest radical form.

Calculators allowed! (though it doesn't need one...)

Bear with me here, I did this all in my head, and I'm a tad rusty on math.

Is it 1728√3 cm3?

... ... ... Quite a bit off. You should do it on paper.

Hint: Formula is: 1/3 BH for the pyramids. You should get an octahedron out of this problem though.

Ohhhh. I accidentally for some dumb reason did the cylinder formula, and as I said, I did this in my head. How did I get the square root, I have no clue.
