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

• 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.

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
