n^3 = 380
We need to solve for n
n^3 = 380
When you have to solve for a variable using its cubic form, you use the cubic root ∛ (Same thing as the square and the square root)
So n^3 = 380
n = ∛380
If you want to check your answer:
n = ∛380
n^3 = (∛380)^3
n^3 = 380
Our answer has been approved.
n = ∛380
n ≈ 7.24
Which means that our final answer is d: 7<n<8
Hope this Helps! :D
