Median: middle number
Mean: average
How to calculate the median:
1) line the numbers in order from least to greatest
0 1 2 4 5 24
(you do not need to write all the fours or fives, one four or five is enough to represent it)
2) Next, take one number off each end at a time until you have one number in the middle left (if there are two numbers left in the middle, add them together, than divide them by two)
3) The median is 4 becuase it is in the middle.
How to calculate the mean:
1) Add all the numbers together
0+24+1+4+5+2+5+4 = 45
2) Now we divide 45 by 8 because there are eight numbers in the list
45/8 = 5
3) The mean is 5.
Answer: Median = 4, Mean = 5

Solution:
Given,
Volume of the-
First cube box=1728 in³
Second cube box=13824in³
We know that volume of cube =a³
So for the first box
a³= 1728 in³
a= 12 in
Now, surface area of the first box
6a²= 6×(12)²
= 864 in²
and for the second box
b³= 13824 in³
b= 24 in
Now, the surface area of the second box
6b²= 6×(24)²
= 3456 in²
Now, the ratio of the surface area of first box to the second box will be
864:3456
=1:4
The surface area of the larger of two boxes is
3456 in²

Have you ever been at the grocery store and stood, staring, at two different sizes of the same item wondering which one is the better deal? If so, you are not alone. A UNIT RATE could help you out when this happens and make your purchasing decision an easy one.
In this lesson, you will learn what UNIT RATES are and how to apply them in everyday comparison situations. Click the links below and complete the appropriate sections of the Unit Rates handout.
