Answer:
Step-by-step explanation:
Given that minimum is 8 and maximum equals 82
Range = 
No of classes =6
Class width = 76/6 ~13
But not given whether variable is discrete or continuous.
If discrete, we have classes as
8-20, 21-33, 34-46, 47-59, 60-72, 73-85
If continuous, we have classes as
8 to <21
21 to <34
and ... ending 73-<86
Since cube has all sides equal and therefor al sides equal aera and 6 sides
SA=6s^2
96=6s^2
divide both sides by 6
16=s^2
sqrt both sides
4=s=y
4 is answer
