### Kaecee's Math Textbook Scribe

The questions I had to do were:
4, 5, and 6

4.) Determine the volume of each right rectangular prism.

a) V = l x w x h
3m x 5m = 15m2
15m2 x 1m = 15m3
V = 15m3

b) V = l x w x h
11m x 12m = 132m2
132m2 x 6m = 792m3
V= 792m3

c) V = l x w x h
4m x 6.2m = 24.8m2
24.8m2 x 2m = 49.6m3
V= 49.6m3

5.) What is the volume of each right rectangular prism?

a) V = l x w x h
2m x 2m = 4m2
4m2 x 10m = 40m3
V = 40m3

b) V = l x w x h
8cm x 7cm = 56cm2
56cm2 x 9cm = 504cm3
V = 504cm3

c) V = l x w x h
11.7mm x 6.3mm = 73.71mm2
73.71mm2 x 2.9mm = 213.759mm3
V = 213.759mm3

6.) Determine the volume of each cube.

a) V = s x s x s
10cm x 10cm = 100cm2
100cm2 x 10cm = 1000cm3
V = 1000cm3

b) V = s x s x s
3cm x 3cm = 9cm2
9cm2 x 3m = 27cm3
V = 27cm3

c) V = s x s x s
2.5cm x 2.5cm = 6.25cm2
6.25cm2 x 2.5cm = 15.625cm3
V = 15.625cm3

* If there are any mistakes please tell me what they are and I'll do my best to fix them.

V= pi.r.r.h
V=(3.14.10.10)40
V=314.40
v=125.60cm3

1. Great job Kaecee! It was well organized and planned out. Two things you could've added was a video and a link about volumes, but overall it was great. Keep up the great work!

2. Nice job Kaecee! Your work is very clear and organized to read, your explaining is very good. I like how you have added the question also, it makes it easier to read and understand. A heads up for next time is that you should maybe add a video or even a link. But yet overall great work and effort, keep it up!

3. Great job Kaecee!
I like how you used colour. Next time you should put some pictures of your work, a link, and a video, also maybe a flisti. Besides that everything is alright, keep up the good work.

4. Good job Kaecee! I liked how you have your work and color. Also, your scribe was easy to understand. Next time, try adding in pictures, links, and videos. But, keep up the good work!

5. Good job on showing you work, and making it clear and organized. Next time you should add colors, a video and link. Keep up the good work!

6. Good Job Kaecee! i liked how you added the questions so it will be easy to understand. Next time add pictures so it will be easy for you,link,and video. Keep up the Goodwork!
