Answer:
B. 2.2
Step-by-step explanation:
Volume of a rectangular prism = length*width*height
You can replace the width with the variable x for now, the height is given in the problem, and the length is 4 times the width so in this case it's 4x.
160 = 4x*x*8
160 = 32x^2
5 = x^2
The square root of five is about 2.2 so B is the correct answer
Answer:

Answer:
Taking data:
28 78 74 89 72
50 55 66 26 84
59 64 88 23 27
70 63 42 37 29
The answer is 
Step-by-step explanation:
As the data is not given in the question i'm guessing the data from the question i solved before
28 78 74 89 72
50 55 66 26 84
59 64 88 23 27
70 63 42 37 29
as taking the above data,



As we know for finding the width of class:


≈ 
Note : By using the above given formula you can calculate the width of any data just by taking the maximum and minimum values of data and the number of classes the data is divided into.
A= base times height
5times 11
55
