A cube has a surface area of 200 square inches. Which choice is closest to the length
2 answers:
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
Where a is the length of an edge
That is :
200 = 6
divide through by 6
200/6 =
that is
= 33.33333333
take the square root of both sides
a = 5.773502692
Therefore the length of an edge ≈ 5.8 inches
