This question actually asked you to make a 3x5 card.
00:05
I recommend using a table.
00:08
I would go to pages 544 and 547 to write down your formulas that are there.
00:39
Volume in general is always the area of the base, is what this capital stands for, times the height.
00:54
And this is for any prism.
00:57
So this is going to be something that makes a right angle from the round.
01:01
So that's going to be your cylinder.
01:05
It has this perpendicular angle here.
01:10
Your cube or your rectangular prism, either one.
01:19
Because again, it makes this right angle.
01:26
When we talk about a cone, then it becomes a little difference.
01:32
When we talk about a cone, because of that.
01:37
Triangular shape there even though it does make that right angle it's going to be one third of that so it's going to be the area of the base which is that circle times the perpendicular height but divided by three and then our sphere is also different again because it's like a ball and so our sphere is going to be four -thirds high r cubed so it takes care of the basics of our volume.

If you need these specific ones to look at them that way and see our area of the circle, please copy them down.
02:31
Then you have surface area...
