Answer: The perimeter is
Step-by-step explanation:
1. By definition, the formula for calculate the surface area of a cube is:
Where s is the lenght of any edge of the cube.
2. You know that the surface area of the cube of the problem is , therefore the lenght of each edge of the cube is:
3. Each face of the cube is a square, therefore the perimeter of one face is:
Answer:
In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system.

Answer:
90.5
Step-by-step explanation:
To get the average, we must add all the values and divide the sum by the amount of them:
- Add (92*5), 94, 85, 85 = 181
- Divide by the number of grades (8): 181/8
The answer will be 90.5, which is his average through all eight tests.
To do this in one step:
