Answer:
24 , 9.333333, 36, 13.3333333
Step-by-step explanation:
12+12=24
28/3=9.3333333333333 (doesn't matter how many you put bc it repeating)
12+12+12=36
40/3=13.3333333333333333 (doesn't matter how many you put bc it repeating)

Answer:
 or
 or 
Step-by-step explanation:
The formula for volume is Base * Height * Width; and the formula for area is Base * Height.
This problem mentions the structure is a cube and therefore it is assumed that every wall has the same area. Since there are 6 sides to a cube you divide the total amount of ft which make up this cube to know the area to each wall.
 = 2.25 or
 = 2.25 or  per wall
 per wall
With the area of each wall you can find the base and height:
base * height =  area

base =  m
m
height =  m
m
since: base=height=width, the width also equals  m
m
volume =  =
=
