Answer:

Step-by-step explanation:
You plug in the points in this equation 
So
= 
V=side^3
64cubicfeet=side^3
cube both sides
4ft=side
difference=8ft-4ft=4ft
the difference is 4ft
?? Elaborate pls and I can’t try to help in comments:)
Find the length of one side.
V = s^3
s = cube root of V
V = 729
s = cube root 729
s = 9
Put this into your calculator as 729^0.333333333
It should bring back 9 or 8.999999 something which means 9.
Net
The net is shown below. You will have to do the labeling. But I can tell you what you should label each face as?
Area of one face = s^2
s = 9
Area of one face = 9*9
Area of one face = 81
So when you draw this, each face should be labeled with 81.
It should have it's units (ft^2) if your marker is picky.
Part C
There are 6 sides.
1 side has an area of 81 ft^2
6 sides have an area of 6*81 = 486 ft^2
