Yeah

It's j- e-explaining that is it's important mathematically, but if my goal is to get them to understand volume, then it is, um, th- I've just put a barrier in front.
18:22
I need them to understand something else before they can understand the volume calculation.
18:27
So that's why if you went down to my slides, it just became volume is area times length.
18:32
That invites a different question, which is two of them, which is, well, isn't that imprecise? And which area do you mean? Well, the which area do I mean is gonna be pretty intuitive based on the diagrams I'm presenting, and it can only really be one 'cause it's the one that is in a rectangle every time.
18:50
Ah, except we started with cuboids, and they're all rectangles.
18:54
So that immediately invites maybe the cuboid is a special case, and it should go at the end rather than the beginning.
