Kenneth's Scribepost for September 28

Hi guys, Today In Math class Day 4 Period 1, Mr.Backe showed us a formula for a cube.

The Formula for the Area of a Cube is 6s (squared).

Mr.Backe also wanted to tell us how we are going to find the Surface Area of a cylinder.

So We talked to each other about what the formula is, and the Surface Area for the cylinder was

S.A. Cylinder: 2 pie r (squared) + 2 pie r (height).

On the Board Mr.Backe used an isometric grid and was drawing a shape like this:

and he was putting numbers on the shape like this:

He also said that "How do I find the answer for x"

then mr.backe gave us the answer or actually we went along with him I think so that we get the answer together. And the answer Is:

x+2=5

x=5-2

x=3

Same thing for Y and eventually we followed Backe and got the answer together or so I think.

Anyways the answer was:

y+2=4

y=4-2

y=2

I want uhh umm uhhhh <.<>.> uhhh Deniel For next scribe

Tell me If I missed anything xD

Surface Area Scribe Post

Hi everyone. On Friday our test was canceled so we learned about finding the surface area of a Rectangular prism, which has length, width, as well as height.

Now. Here is a rectangular Prism, with some random numbers. Today the unit I am going to use is centimeters.

The length is 2 cm, the width is 5cm, and the height is 3 cm.

Formula: 2(lw)+2(lh)+2(wh)
2(2cm x 5cm) = 20, 2(2cm x 3cm) = 12, 2(5cm x 3cm) = 30cm
20+12+30 = 62
Our surface area is 62 cm2

If my answer is wrong, please correct me. Basically, all I did was follow the formula. Thanks for reading. And don't forget to study for the test we have on symmetry tomorrow.
