The measured data is
x=[10.56, 9.52, 9.73, 9.80, 9.78, 10.91].

Calculate the mean.
m = (10.56+9.52+9.73+9.80+9.78+10.91)/6 = 10.05

Calculate the deviations from the mean.
k = x - m
   = [0.51, -0.53, -0.32, -0.25, -0.27, 0.86]

Calculate the absolute deviation from the mean.
d= \frac{1}{6} | (0.51-0.53-0.32-0.25-0.27+0.86) | = |1.184\times10^{-15}| \approx 0

Answer: 2300. 

Explanation:
There are 1000 millimeters in a meter. 
There are 100 centimeters in a meter. 
There are 10 millimeters in a meter. 

Multiply the number of meters by 1000 giving us 2000. 
Multiply the number of centimeters by 100 giving us 300. 

Add the numbers together to get 2300. 

Bonus info 
Milli: 1000
Centi: 100

That information should probably help you with other measurement conversions when you take chemistry or physics. 

Have a nice day! :) Good luck with the rest of middle school.
