Question

The volume of a child's model plane is 1200 cm^3
The volume of the full size plane is 4050 m^3

Find the scale of the model in the form 1:n

Answer 1

will be


4050/1200 = 405/120 = 81/24 = 27/8 = 1/n

27/8 = 1/n cross multiplie

27n=8

n= 8/27

result this scale will be 1/(8/27)

hope is understandably

Answer 2

but 4050 m3 should be changed to cm3 right?

Answer 3

@jhonyy9

Answer 4

oh yes sorry i missed it

Answer 5

or invers 1200 cm^3 = ? m^3

Answer 6

1 m^3 = ? cm^3

Answer 7

=1,000,000 cm^3

Answer 8

so 4050m^3 would be 4,050,000,000?

Answer 9

yes right but i think will be more easy without this so great numbers than you change 1200 cm^3 in m^3

how you think it ?

Answer 10

but you can rewrite this result using 4*10^9 (standard form)

Answer 11

so 4050m^3 would be 4,050,000,000

Answer 12

yes

Answer 13

so 4050m^3 would be 4,050,000,000 = 4*10^9

yes ?

Answer 14

or 1200 cm^3 = ? m^3

Answer 15

1200 cm^3=0.0012 m^3

Answer 16

rewrite it using power of 10

Answer 17

1200 = aproximatly 1*10^3

Answer 18

1.2x10^-3

Answer 19

n=4*10^9 / 10^3

Answer 20

yes 1,2*10^-3 but you can consider it 1*10^-3 = 10^-3

ok ?

Answer 21

okay

Answer 22

so than will result


1/n = 10^-3 / 4*10^9

n=?

Answer 23

so n= ?

Answer 24

2.5*10^-13?

Answer 25

umm

Answer 26

but the answer is supposed to be n=150
:/

Answer 27

yes but you need writing your answer in this 1/n form

Answer 28

ok

Answer 29

isnt it supposed to be related to that?

Answer 30

so than us this 2,5 *10^-13

so than from 2,5/4 you will get 0,6

because 1/150 = 0,006 = 6*10^-3
