Answer: C. 5.8 inches
Step-by-step explanation:
The formula for calculating the Surface area of a cube is give as :
surface area = 6[tex]a^{2}[/tex]
Where a is the length of an edge
That is :
200 = 6[tex]a^{2}[/tex]
divide through by 6
200/6 = [tex]a^{2}[/tex]
that is
[tex]a^{2}[/tex] = 33.33333333
take the square root of both sides
a = 5.773502692
Therefore the length of an edge ≈ 5.8 inches
