A cube has a volume of 216 cubic inches. What is the length of each edge of the cube?

Answer:
Each side is 6 units.
Step-by-step explanation:
The problem is not how to do the question. The problem is how to get your calculator to do the question.
V = s^3
s = ?
V = 216
So what you need is the cube root of 216
s^3 = 216
cube root(s^3) = cube root(216)
s = cube root 216
Your calculator should have a y^x or x ^y key.
Put in 216
Press the y^x key or the x^y key
Put in 0.33333333333
You should get something like 5.999999 which you should round to 6.
