Arun's Volume scribe

4. a) V = b x h x l
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
V = 15. 625 cm3
