### 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.
