Help me please on this

Step-by-step explanation:

I'll leave you to do the labeling. The rectangle defined by 0,0 and 3,7 is the area that you are interested in. The maximum is at x = 3 and y = 7

P = 2*3 + 3*7

P = 6 + 21

P = 27

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
