Answer:
20 cm
Step-by-step explanation:
A cube has 6 faces. Two of the faces are bases. The other four faces are lateral faces.
Let the area of 1 face = x
4x = 1600 cm^2
x = 400 cm^2
Since the area of 1 face is 400 cm^2, then the side length is sqrt(400 cm^2) = 20 cm
Answer: 20 cm
To get rid of the parenthesis, we use the Distributive Property.
8x + 4x - 4
Now, we add the like terms.
12x - 4
The answer is B, 12x - 4. You were really close!
Hope this helps!
