In class we measured books with 1cm cubic centimeter squares, and we were trying to find the surface area and the volume of the book.

Here are a few examples..

A Hey B.C Book.

Example 1...

**Note Before Reading**
If you do not understand Surface Area, Please look at Iseralie's or Kevin's Scribe below mine!!

Here is the Net of the B.c Book..

Now we have to find the Surface Area.

SA= 2(hxl)+2(hxw)+2(LxW)
Sa=2 (18x1)+2(18x10)+2(1x10)
SA=2 (18)+2(180)+2(10)
SA= 36 + 360 + 20

SA= 416cm2

Here is the Volume..

Volume of a Rectangular Prism
LxWxH---------*THIS IS THE FORMULA!!!

1cm2 x 10cm2 x 18cm2 = 180cm3

Or....
Area of Base X Height
*Area of the base multiplied by the height is another way to get the volume of a rectangular prism or a cube!


(10cm2) 18cm2 = 180 cm3

Example 2

Here is the Net of A Dictionary...

*Note.. Its Recommended that you click on the Pic to See the Picture and the Math Work Better.

Here is the Volume of the Dictionary

Volume of a Rectangular Prism
LxWxH ---------*THIS IS THE FORMULA!!!

5cm2 x 11cm2 x 19cm2 = 1045cm3

Or....

Area of Base X Height
*Area of the base multiplied by the height is another way to get the volume of a rectangular prism or a cube!

(55cm2)19cm2 = 1045cm3

Today in class, we had to find out the surface areas of different shapes. We had to make nets for the 3D shapes and then we drew the nets on grid paper. Then we cut them out and glued them in our notebooks.

Three of the six shapes that we did in class:

Today we were working with our groups to find diffrent surface areas with shapes such as squares, rectangles, and triangles of diffrent shapes. What we are going to do next is we are going to look at 3 of the shapes we did in class.
We traced all of the shapes out on grid paper and glued it into our note books....
*Make sure to lable all the sides




The first one I did was finding the surface are of a rectangle.I started by making a net of the shape. Each of the cubes are one centimeter all around so it was easy to find the lenght of each side. Once you have determined the side lenghts all you have to do is add them up to get the size of the box.

After you have the sizes of all the boxes you make a formula to find the surface are.

Formula For surface area....

SA = 16(2)+8(4) =

32 + 32 = 64 cm2

----------------------------------------------

*Make sure you lable all the sides

There are 2 in this next set.
This explination is for the larger one ......You start by making the net. Then the next step is to add up all of the sides and determine a the size of each square or rectangle. Now we can make a formula for finding the surface area.
Formula............


SA = 2(4)+2(8)+2(32) =
8 + 16 +1024 =
SA= 1048 cm 2
This set of instructions are for the smaller picture.....
Draw the net on your grid paper and find the side lenghts and the size of the squares. Once you have all of the sizes you can start to figure out your formula.Formula.........

SA = 4(8) + 2(4) =

32 + 8 = 40 cm2

SA = 40 cm2
Make sure you have all of the notes and nets and everything you need to get 12 free markes. To get the rest of the shapes go and see Israelie's scribe.

Pythagorus Triple

There is a bunny and it is trying to get to his bunny rabbite stack of carrots, but to get there the bunny must hop five times forward but hop three times to the left. When the bunny get's that far how far did the bunny have to hop to get there.

Chris's Pythagoras growing post

Part 1:Describe what a Pythagorean Triple is and use your perfect square chart from 1 squared to 10 squared to find another one other than 3,4,5.

A Pythagorean Triple is 3 unknown numbers a, b,c that work with a2, b2=c2

Part 2:Using embeddable web 2.0, describe how to find the missing side of a Right Triangle using the Pythagorean Theorem, show how to solve both for a missing leg and the hypotenuse (note: you may use numerical examples ie. a=4 b=6 c=?)


Part 3:Explain how to solve a Pythagoras word problem. Use one of the examples we covered in class

Problem B
You’ve just picked up a ground ball at first base, and you see the other team’s player running towards third base. How far do you have to throw the ball to get it from first base to third base, and throw the runner out?



Part 4:Now that you have seen many Pythagorean problems, create your own word problem.

kyle's pythagorean growing post

Question 1:

Describe what a Pythagorean Triple is and use your perfect square chart from 1 squared to 10 squared to find another one other than 3,4,5.

A pythagorean triple is three numbers that are all perfect squares. Like 3 squared + 4 squared equals 5 squared. So, then it is 9 + 16 = 25. Another pythagorean triple from the perfect square chart is 6,8,10.

Question 2:

Using embeddable web 2.0, describe how to find the missing side of a Right Triangle using the Pythagorean Theorem, show how to solve both for a missing leg and the hypotenuse (note: you may use numerical examples ie. a=4 b=6 c=?)

Question 3:

Explain how to solve a Pythagoras word problem. Use one of the examples we covered in class (Worksheet A, B, LeFrog or Bonus Problem).

Mr. H jumped into a canoe to cross a river that runs east to west and is 20m wide. The current carried him down stream 8m before he reacked the other side. How far did he travel?

Question 4:

Now that you have seen many Pythagorean problems, create your own word problem.

Mr. Smith a 10ft. ladder and has to climb up a 8ft. wall. How far away fron the wall does Mr. Smith have to place the ladder?

Part 1:
QUESTION 1:
What is a Pythagorean Tripple?

Pythagorean triple are three unknown numbers: a, b, and c. They follow the formula a²+b²=c². A and B are the legs and c is the hypotneuse.

FORMULA: a²+b²=c²

Example:

a=8 a²+b²=c²

b=6 8²+6²=c²
c=? 64+36=c² ---------------------->
100=c²
√100=√c²
