# Pyramid vs Cube

Make a pyramid that looks like this:

- It has a square base
- Its apex (top point) is directly above one corner
- Its height (the distance from that corner to the apex) is the same as the base length

You can print out this template to help you:

Now make two more exactly the same, so we have three:

Fit them together and we get a cube:

So **three** of those pyramids exactly make one cube!

And so the volume of that **pyramid is exactly one third** of a cube.

We can extend that idea to come up with the volume of a general pyramid:

Volume = \frac{1}{3} × [Base Area]× height

And, by thinking that a cone is just like a pyramid with a ridiculous number of sides, we can come up with the volume of a cone:

Volume = \frac{1}{3} π × r^{2 }× h

Isn't mathematics wonderful!
