V = 1 x3 x 5

1 x 3 = 3 cm2

3 cm2 x 5 cm2 = 15 cm2

V = 15 cm3

b)V = b x h l

V = 11 x 6 x 12

11 x 6 = 66 cm2

66 cm2 x 12 cm2 = 792 cm2

V = 792 cm2

c) V = b x h x l

V = 4 x 2 x 6.2

4 x 2 = 8 cm2

8 cm2 x 6.2 cm2 = 49.6

V = 49.6 cm2

5. Questions: Answer:

a) l = 2 m, w = 2 m, h = 10 m a) l x w = b V = b x h

b) l = 8 cm, w = 7 cm, h = 9 cm V = 80 cm3

c) l = 11.7 mm, w = 6.3 mm, b)l x w = b V = b x h

h = 2.9 mm V = 4, 032 cm 3

d) l = 6.2 cm, w = 6.4 cm, h = 6.4 c c)l x w = b V = b x h

V = 213 , 759 cm3

d) l x w = b V = b x h

V = 253, 952 cm3

6. a) V = s x s x s

10 x 10 x 10

V = 1000 cm3

b) V = s x s x s

3 x 3 x 3 V

V= 28 cm3

c) V = s x s x s

2.5 x 2.5 x 2.5

Sorry the answers got mixed up when I posted it.

ReplyDeleteNext time add the question that you are answering to because it was a little confusing. Also I would suggest you add a picture, link, and/or video next time. Good job on adding the formulas.
