Can someone plz help me

6.28318530718

We know that any time a number is next to a math sign it means to multiply.

                   Any time you see this symbol "π" it means 3.14.

So, 2 times 3.14 is equal too 6.28318530718 or it can be rounded too  6.28

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

actually what is a question i don't understand
