The area of the room is 
square feet so Michelle's reasoning was incorrect.
Step-by-step explanation:
Step 1:
To calculate the area of the given room, we divide the unknown shape into known shapes.
The room's shape is made of 2 rectangles.
The area of a rectangle is the product of its length and its width.
One rectangle has a length of 10 feet and a width of 
feet.
The other rectangle has a length of 
feet and a width of 
feet.
Step 2:
The area of the first rectangle 
square feet.
The area of the second rectangle 
square feet.
The total area of the room 
square feet.
The area of the room is square feet so Michelle's reasoning was incorrect.
Use decimals 1/3= 0.33 1/2=0.5 . 2/2= whole hour=1 multiply 1/3 times 2 and he would mow 0.66=2/6 of his yard in an hour.
1 yd 2 ft
* 8
----------------
8 yd 16 ft
but we can reduce 16 ft
there are 3 ft in a yd
16/3 = 5 yds with 1 left over
8 yds 16 ft = 8 yds + 5yds 1 ft
13 yds 1 ft
If I'm really it correctly, V = 5^3
v = s^3
s = 5
V = 5*5*5
V = 25*5 That's 2 fives multiplied together.
V = 125 cubic units.
