A.
a= V^1/3 = 12167^1/3 = 23cm
The height = 23cm
B. Area of one face of the cube = =
= 3174
Step-by-step explanation:
A. To find the height of the cube, I used the cube root of the given volume, since the volume of a cube is equal to the cube root of its length/height
B. To find the area of one side of the cube, I sustitute S for the side length/height of the cube, which is 23cm. Then I multiplying the length of the cube's side by its width to find its area, since the length and width of a cube's side is the same.
Answer:
Option C is correct.
Step-by-step explanation:
We have been given total 8 data
Data is : 12,15,18,20,23,23,28
Here, n=7
Median is
Median is 20.
When one data is added n=8
The median of even number of data is
Median is
Median is
4th terms is 20
5th terms is 23
Since, median should not be change hence,
Median will be 20.
Therefore, option C is correct.
