Ashton's surface area and volume post

alright so for this blog it will be a little different for my work i made them into videos here are the links

the rectangle
http://www.youtube.com/watch?v=fZRVXMEe8YQ&feature=youtu.be
the triangle
http://www.youtube.com/watch?v=_3Azr5x7XB0&feature=youtu.be

And the cylinder

Here's a link and a video that might help you understand more about finding the Total Surface Area of a 3 dimensional shape.

Isabel's Surface Area and Volume Post

#1: Rectangular Prism
Shape

l(length) x w(width)
- Front: 10m by 6m
- Top: 10m by 5m
- Side: 5m by 6m

Net

l(length) x W(width)
- Front: 10m by 6m
- Top: 10m by 5m
- Side: 5m by 6m

Surface Area

l(length) x w(width)

- Front: 10m by 6m= 60m

- Top: 10m by 5m= 50m

- Side: 5m by 6m= 30m

TSA= 2x (F+T+S)

= 2x (60+50+30)

= 2x (140m)

= 280 m2

#2: Triangular Prism

Shape

Net

Surface Area
- 5 x 27= 145 cm

- formula: bxh/2

8x9/2

72/2

36 cm

- 145+36+36= 207 cm2

#3 Cylinder
Shape

- Diameter 8 mm

- Rectangle 12mm

Net

Surface Area

Please do correct me if I did something wrong. But, I hope this post will help you to improve your skills :D

Sorry that you can't see some of them because I used pencil but next time I will really take the time to outline it with dark marker.

Volume

Cyerra's Surface Area Post

Cylinder

Triangular Prism

Rectangular Prism

Cylinder Volume

Radius = 5 cm
Height = 23 cm
3.14 x 5 x 5 = 78.5
78.5 x 23 = 1805.5 cm

Rectangular Volume

L x W x H
1 x 3 = 3
3 x 5 = 15

Triangular Volume

7 x 7 = 49
49 / 2 = 24.5
24.5 x 12 = 294

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

Find 3 fifths:
294 / 5 = 58.8
58.8 x 3 = 176.4
