Erick's Scribe

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...

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
