Answer:
answer is 0
Step-by-step explanation:
You work backwards. Starting with 2/3, you subtract 1/3 to get m/3=1/3.
A cube has 6 sides. Divide the surface area by 6 to get the area of one side:
13 1/2 /6 = 2 1/4
The area of one side is S^2
To fins the length of the sides find the square root of the area:
Side = sqrt(2 1/4)
Side = 1 1/2 cm.
