So this would be a cross section.

So that's the area of each cross section.

See, you can tell by the cross section.

So a cross section perpendicular to the x axis.

So if we were to take a cross section, so let's say that this, let's take this cross section of the pond.

So we're still dealing with if we take a cross section, if we were to cut this figure this area would be the cross section.

Imagine some device where this is kind of a cross section.

For this solid each cross section perpendicular to the x axis.

Say we took this cross section of this solid right now.

You're actually looking at the cross section of a memory right now.

What does a cross section at any point of the pond look like?

For this solid each cross section perpendicular to the x axis is a square.

So they say, each cross section perpendicular to the x axis is a square.

If I have, I'll try to color code it, if I have A cross

If we took the cross section there, it would be a small square as well.

So it says for this solid, each cross section perpendicular to the x axis, right?

So that you can imagine this little bit of a cross section, it's a little bit of a cross section of this solid so this disc right over here is going to have some area.

So if we took the cross section of the solid here it would be like that.

So if I were to draw, let me see if I can draw this cross section.

You have the circle that's kind of the cross section of the doughnut at any point.

So the cross section, the top of the doughnut, we're going to start off right over here.

that is a second section, and then a third section, fourth section, and then we have a fifth section.
