1 meter = 100 cm, so 10 m = 1000 cm and
0.1 m = 0.01
To change meter into centimeter you MULTIPLY the meters by 100
And to convert cm into meter you DIVIDE the cm by 100
5 times 20(which is your number of days) equals 100. Louis already had 25 so add both numbers together to get 125
10 x 10 x 10, I believe this is the form you mean.
