Question in comments:P
Alright. If I were to give you a side length of a cube, and to solve for the volume from there, would you be able to do that?
uhhhhh. nope.
Okay that's fine
So, what is a cube? If I gave you a box and I told you it was a cube, what are some things you could say about it?
Anything at all, it doesn't even need to be relevant to the problem. What makes a cube a cube?
The shape.
That's good. What about the shape?
It has all same size sides
Right perfect. So, what is volume exactly?
I dont know :(
Oh okay that's fine. Do you know what surface area is?
Or, do you know what area is in general?
If I told you to find the area of this square, could you do that? |dw:1444859352456:dw|
Lw i believe
3x3=A
Okay yes, that's great. Exactly right. So the area would be A. Now, if I told you that a perfect square has an area of 16, would you be able to figure out the length of the sides?
8
So the square would look like this? |dw:1444859454212:dw|
yes.
So if we use your length times width formula, we have 8x8 = 16?
yes.
What is 2x8?
wait. i feel stupid.
Its fine haha. So yeah, keep in mind that area is multiplication not addition.
So, starting over, if I told you the area of a square is, say, 25 Could you find the length?
Im still rlly confused.
Its okay, we're starting off with something simpler. A square has area 25. You know that a square has all sides equal. Can you figure out the length?
12.5?
You're dividing by two again. That didn't work when the area was 16 did it?
Ughhhh
Okay so, length times width. = Area right?
yes.
Because Length = width for a square, we have LxL = A LxL = 16
Can you think of an L that makes that true?
No. Im terrible at math. Just forget it. Sorry to waste your time. And thanks for trying to help.
No no its fine. We're making progress
Okay. I'm going to draw a few that we already know the answer to, and we'll see if we can find a pattern
Okay. But im never going to get this.
