Question

How to convert from cubic meter (m^3) to millimetre (mm)?

Answer 1

1 m = 1000 mm
(1 m)^3 = (1000 mm)^3

Answer 2

1 m^3 = 10^9 mm^3

Answer 3

For instance how many mm of rain to fill 30.9 m^3?

Answer 4

You mentioned twice m^3 and mm, not mm^3.
To convert m^3 to mm^3, multiply m^3 by 10^9
30.9 m^3 * 10^9 mm^3/m^3 = 3.9 * 10^10 mm^3

Answer 5

In the text they tell me to convert from m^3 to mm

Answer 6

Textbook*

Answer 7

In other words, how many mm of rain to fill three water tanks whose total volume is 30.9m^3?

Answer 8

It says in the textbook regarding the last question "when rain falls it is measured I'm millimetres. This means that this is the depth to which the water would fill if it were captured. Use the formula V=AH to find the number of millimetres of rain that must fall on the roof to fill the tanks.

Answer 9

Total volume of the three tanks is 30.9m^3

A rectangular rooftop has dimensions 17m x 10m providing water to the three tanks (each with a radius of 1.25m and a height of 2.1m

Answer 10

What are the dimesions of the roof?

Answer 11

I sent you the dimensions

Answer 12

Ok, I see it.

Answer 13

You are correct, the total volume of the three tanks is 30.9 m^3

Answer 14

I solved the first three question and that was one of them

Answer 15

The volume of a prism that has as base the roof has a volume of
V = LWH
We know the volume is 30.9 m^3, L = 17 m, and W = 10 m; we need to find H

Answer 16

H = V/(LW)
H = (30.9 m^3)/(17 m * 10 m)

Answer 17

H = 0.18 m

Answer 18

30.9m^3/170m^2?

Answer 19

Correct

Answer 20

I'm with you.

Answer 21

Once you get H, you'll have the height in meters. Then you need to convert it to mm.
To do that, keep in mind that 1 m = 1000 mm, so multiply the height in meters by 1000 to get it in mm.

Answer 22

I see

Answer 23

Could you please show it to me. I'm not that confident when it comes to converting units

Answer 24

Also I have one last question that is driving me nuts :)

Answer 25

Did you get H = 0.18 m?

Answer 26

Yes I understood where it came from thanks to you

Answer 27

Just take the height and multiply it by 1000:
0.18 m * 1000mm/m = 180 mm

Answer 28

Thanks a lot for your help. I've got a something similar to this question if you don't mind helping me

Answer 29

go ahead. pls start a new post. i'll look for it
